Simplify the given equation. 5x + 2(x - 3) = -2(x - 1)
svp [43]
On the left side, distribute the 2 to x and -3 so the left side should look like 5x+2x-6.

on the right, distribute the -2 to x and -1 so the right side should look like -2x+2.

combine like terms on the left to get 7x-6=-2x+2

add -2x from the right side to the left side to make the equation 9x-6=2 now it's a two step equation.
add 6 to 2 to get 9x=8. divide by 9 and x=8/9.
