4-2-x= -10

so what you’re going to do first is flip it to 4+-2+-x= 10 (to make it easier. you dont have to though………). then you are going to get rid of the 4 by subtracting 4. because the opposite of addition is subtraction. and wat is done on the left HAS to be done on the right. so you subtract 4 from the 10 also.

example:

4+-2+-x=-10

-4 -4

now youre left with:

2+-x=-14

now you need to get rid of the 2 so the x can be alone. one again you subtract because subtraction is the opposite of addition, then you subtract from the the 6 because what u do on the left has to be done on the right.

Example

2+-x=-14

-2 -2

now your left with::

-x=-16

since its a -x, you have to make the 16 a positive (because – x – = positive) though so the answer is:::

x= 16

and you should know how to check it 😉

So you have 4-x=10. To get the x by itself, first, you need to subtract four from both sides. Anything you do to one side, you need to do to both, so…

4-x-4 = 10-4

-x = 6

Last, since you have a -x instead of x, you need to switch the signs of everything. Thus, you get

-x = 6

x = -6

Viola.

now, take the known numbers ( like the numbers 6,2,10) to one side and keep the unknown( which is x here) in other side

suppose u keep x in left hand side(LHS) n move other numbers

it is a rule that when u move a numbr in other side then the sign infront of it changes

-x=10-6+2 , u see earlier in eqn -(i) there ws ‘+’ sign infront of 6 but nw we put ‘-‘

-x=6

u can write it as

x= -6

4 – x = 10

– x= 6

x = -6
