Answer:

x = -8

Explanation:

First, we want to take care of the multiplication on the second half, so we can more easily manipulate the sides:


4x-5(x+6) = 4x - (5x + 30) = -x - 30

With that out of the way, we can start isolating the sides:


3x+2 = -x - 30


3x+2(+x) = -x - 30(+x) = 4x+2 = -30


4x+2(-2)=-30(-2) = 4x = -32

Now that we have x isolated, we can divide both sides by 4 to get our answer:


4x(/4) = -32(/4) = x=8


x=-8

Answer:

x = -8

Explanation:

3x+2 = 4x-5 (x+6)

=> 3x+2 = 4x-5x-30

=> 3x-4x+5x = -2-30 (arragning the like terms together)

=> 4x = -32

=> x = -32/4

=> x = -8
