Solve for x: −3|2x + 6| = −12
−3|2x + 6| = −12−3(2x + 6) = −12-6x - 18 = -12 -6x = -12 +18 -6x = 6 x=-1−3 [-(2x + 6)] = −12−3 (-2x - 6) = −12 6x +18 = -12 6x = -12 -18 6x = -30 x=-5answer: x= -5 and x = -1
-3 | 2x + 6 | = -12| 2x + 6 | = -12/-3| 2x + 6 | = 42x + 6 = 4 -(2x + 6) = 42x = 4 - 6 -2x - 6 = 42x = -2 -2x = 4 + 6x = -1 -2x = 10 x = -5solution is : x = -1 or x = -5
