Hey there! :)

-9 - 4x = 7 ; find x.

In order to find the value of x, we must isolate the variable. This simply means that we need to get x alone on its own side of the equal sign.

We can start by adding 9 to both sides.

-9 + 9 - 4x = 7 + 9

Simplify!

-4x = 16

Then, divide both sides by -4.

-4x ÷ -4 = 16 ÷ -4

Simplify.

x = -4

Your final answer is : x = -4

Hope this helped! :)
