Original equation: -4(x - 3) = -x Distribute -4 over terms in parens on left side: -4x + 12 = -x Get rid of -x on left side by adding x to both sides: -3x + 12 = 0 Get rid of +12 on left side by subtracting 12 from both sides" -3x = -12 Get rid of -3 in front of x on left side by dividing both sides by -3 to solve for x: x = 4
