Question

solving the given equation:
-2+4(x-1)=-7-4x

Answer 2

I believe the book gives x=1/8 I need to know the steps

Answer 3

can you help me

Answer 4

-2-4+4x = -7-4x
-6 + 4x = -7 -4x <-- you have "6+4x". Watch those signs, theyll mess you up everytime.

-6 +4x = -7 -4x
-6 +7 = -4x -4x
1 = -8x
(-1/8) = x
