# Math! help pleasee.?

I don’t understand how to do this, been trying to much.

7+s

——— = -4

5

and

2/3 – 6h = -11/6

Please tell me the steps to understanding this pleasee.write it all out for me,i do not understand.

multilpy both sides by 5..

the 5s in lhs gets cancelled

u get 7+s= -4*5

s= -27

ii)multiply by 6

4-36h= -11

36h=15

h=15/36=5/12

For the first problem, multiply both sides by 5, then you have:

7 + s = -20

Now, subtract 7 from both sides

s=-27

For the second problem, subtract 2/3 from both sides:

-6h = -11/6 – 2/3

You will need to simplify the right side, so make common denominators. Multiply 2/3 by 2/2. You can do this because 2/2 equals 1 and multiplying any number by 1 won’t change the original number.

(2/3) x (2/2) = 4/6

Now…

-6h = -11/6 – 4/6

then add -11/6 and -4/6

-6h = -15/6

Now divide by -6

h = 15/36 = 5/12

7 + s

——- = -4

5

Multiply both sides by 5 to get rid of the fraction. (5 x 1/5 = 1)

5 (7 + s) = -4(5)

——–

5

7 + s = -20

Subtract 7 from both sides

7 + s – 7 = -20 – 7

s = -27

2) 2/3 – 6h = -11/6

The easiest thing to do in this case is to multiply everything by 6 to get rid of the fraction 11/6.

2/3(6) – 6(6h) = -11/6(6)

4 – 36h = -11

Subtract 4 from both sides:

4 – 36h – 4 = -11 – 4

-36h = -15

Take out the LCM, in this case -3:

-36h/-3 = -15/-3

12h = 5

Divide both sides by 12:

12h/12 = 5/12

h = 5/12

You can check this one by substituting:

2/3 – 6(5/12) = -11/6

2/3 – 5/2= -11/6

4/6 – 15/6 = -11/6

-11/6 = -11/6

I would multiply both sides by 5 to get rid of the fraction first

7 + s = -20

Subtract 7 from each side to get s alone

s = -27

Check:

7 -27/5 = -4

-20/5 = -4

-4 = -4

For the second one I would multiply the entire thing by 6 to get rid of the fractions (6 beinc the common den. for 3 and 6)

4 -36h = -11

Subtract 4 from both sides to get the -36 h alone

-36h = -15

Divide through by -36 to get the h alone

h = 15/36

Reduce the fraction

h = 5/12

when you have problems like this, the goal is to get your variable on one side, and the constant(s) on the other. for the first problem, you need to get the 5 on the other side by multiplying both sides by 5. at that point you simply have a constant plus the variable on the left side. From here you just subtract 7 from both sides. Whatever number that gives is your answer.

For the second one, you actually have the same number of steps. You subtract the 2/3 from both sides, the divide both sides by -6 and this yields you answer.

It wont be long before this stuff comes naturally, good luck

i dont know the first one but you subtract 2/3 from -11/6 which is 3 then you divide -6h by 3 which is -2.

So h=-2.

Hope that helps.

1.)

multiply each side by 5. on the left side of the equal sign you will be left with 7+s (the 5’s will cross out) and on the right side, you will be left with -20.

7+s= -20

next you must subtract seven from each side. on the left side you will be left with s and on the right side you will be left with -27 so…

s= -27

2.) subtract 2/3 from each side and you will be left with 6h on the left and on the right 1 1/6.

6h= 1 1/6

next divide each side by 6. on the left you will have h and on the right you will be left with 7/36 so….

h= 7/36

i hope that helps

uh well for the first one you gotta multiply the whole thing by 5 and then you’ll get 35 + s = -20 and then you subtract 35 to both sides and then you get s = -55.

idk bout the second one. but good luck! =)

i think s +-14 im not sure about the other 1

i think your supposed to divide 5 on both sides and break it down like that. same for h
