What value of x makes the equation -5x - (-7 - 4x) = -2(3x - 4) tru

Well, you’re going to start by simplifying each side of the equation.

This step makes sure that you know to distribute the negative.

-5x + [-(-7-4x)] = -2(3x-4)

Continue to simplify. Start by distributing across the parentheses.

-5x+(7+4x)= -6x+8
-5x+4x+7= -6x+8
-x+7=-6x+8

Once you can’t simplify either side any more, you try and isolate the variable onto one side.

-x+7=-6x+8
+x. +x

7=-5x+8

Then isolate the constants into one side.

7=-5x+8
-8. -8

-1=-5x

Then make sure you have the variable being multiplied only once.

-1= -5x
—. —
-5. -5

0.2=x

And then move your variable to the left.

x=0.2

The value of x that makes the equation true is 0.2

I hope that helps!!
