Answer

$x=-1$

Work Step by Step

Distribute 2 on the left side and 3 on the right side to obtain: $2x-2+3=x-3x-3$ Combine like terms on each side of the equation to obtain: $2x+1=-2x-3$ Add $2x$ on both sides of the equation to obtain: $4x+1=-3$ Subtract 1 on both sides of the equation to obtain: $4x=-4$ Divide 4 on both sides of the equation to obtain: $x=-1$
