17*x + 17 = 8*x + 2 Take 8*x away from both sides 9*x + 17 = 2 Take 17 away from both sides 9*x = -15 Divide both sides by 9 x = -15/9 = -5/3 = -(1+2/3)

3x + 17 + 5x = 7x + 10Combine (add) the 'x'-terms on the left side of the equation:8x + 17 = 7x + 10Subtract 17 from each side:8x = 7x - 7Subtract 7x from each side:x = -7
7x+x = 8x
8x-2 = -9+7x8x-7x = -9+2x=-7
x=1
