How do you solve the equation 3parentheses x minus 8 parentheses plus 7 equal 2 x?

3(x-8) + 7= 2X
3X-24+7= 2X (distribute 3 within the parentheses)
-17= 2X-3X (Here I combined two steps. -24+7=-17 and I moved 3X to the other side. Technically I subtracted 3X from both sides.
-17=-X (subtract 2X-3X)
X=17 (X is not allowed to be positive, so remove the - sign from both sides)
