Solving for x 5x - 8 = 2x + 7 subtract 2x from both sides 5x - 2x - 8 = 2x - 2x + 7 3x - 8 = 7 add 8 to both sides 3x - 8 + 8 = 7 + 8 3x = 15 divide both sides by 3 3x/3 = 15/3 x = 5 Check answer by replacing x with 5 in the orginal equation 5x - 8 = 2x + 7 5(5) - 8 = 2(5) + 7 25 - 8 = 10 + 7 17 = 17
