# Math! help pleasee.?

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.

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

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

——- = -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

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

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

So h=-2.

Hope that helps.

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

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

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