$x = -3$

First expand everything in parenthesis:

$-2x - 18 - 9 + x + 2 = 2x - 1 + 5x$

The group like terms on each side of the equation:

$-x - 25 = 7x - 1$

Then solve for $x$ while keeping the equation balanced:

$-x + x -25 + 1 = 7x + x - 1 + 1$

$-24 = 8x$

$x = -3$

How do you solve -2(x+9) -(9-x) +2= 2x-1+5x-2(x+9) -(9-x) +2= 2x-1+5x?
