Let's first simplify the equation |2x + b = a by considering two cases: Case 1: 2x + b>0 In this case, 2x + b = 2x + b, so the equation becomes 2x + b = a, which can be rearranged to solve for x as . (1) x = a-b 2 ***..... Case 2: 2x + b < 0 In this case, 2x + b = - (2x + b), - (2x + b) = a, which can be rearranged to solve for x as x = so the equation becomes : b-a 2 (2) ? Why don't, X = -a-b 2
