2(x – 3) + 5x = 5(2x + 6) --------------------------------------------------- Distribute (2)(x)+(2)(-3)+5x=(5)(2x)+(5)(6) 2x+-6+5x=10x+30 --------------------------------------------------- Combine the like-terms (2x+5x)+(-6)=10x+30 7x+-6=10x+30 7x-6=10x+30 --------------------------------------------------- Then, subtract 10x from each side 7x-6-10x=10x+30-10x -3x-6=30 --------------------------------------------------- Add 6 to each side -3x-6+6=30+6 -3x=36 --------------------------------------------------- Divide each side by -3 -3x ÷ -3 = 36 ÷ -3 x = -12
