If x ≠ 2.5 and 2x = |15. Add 4x to both sides: 15 = 6x Solve: x = 15/6 = 5/2 = 2.5 Since we're told x ≠ 2.5, we can stop pursuing this case Take: 15 - 4x = -2x Add 4x to both sides: 15 = 2x Solve: x = 15/2 = 7.5 NOTE: Since we've already seen that x = 2.5 is NOT a solution, we can be certain (without testing) that the correct answer must be x = 7.5
