7x + 19 = -2x + 55Add 2x to both sides:9x + 19 = 55Subtract 19 from both sides:9x = 36Divide both sides by 9x = 4

55 - 2X = 7X + 19 add 2X to each side 55 = 9X + 19 subtract 19 from each side 36 = 9X divide each sides integers by 9 4 = X ------------check in original equation 55 - 2(4) = 7(4) + 19 55 - 8 = 28 + 19 47 = 47 ----------------checks

It is: 55+19 = 74

Yes.

x is your number, so 2x + 17 =55. Solving for x = 19

does 41 +_=55

32 + 40 + 55 + 33 = 160
