If we add 51 and 17 (51 + 17), we'd get 68 for an answer. The number 51 is 50 + 1, and the number 17 is 10 + 7, taking the units digits, 1 + 7 equals 8, and 50 + 10 equals 60. Further, 8 plus 60 is 68, so the sum of 51 and 17 is 68.

25x+3x+21 = 32+51+9 Collect all like terms together and notice the change from +21 to -21, this is done in order to keep the equation in balance. 25x+3X = 32+51+9-21 28x = 71 Divide both sides of the equation by 28 to find the value of x: x = 71/28 or 2 and 15/28 x = 2.535714286 as a decimal
