Step-by-step explanation:
3(7 + 2x) + 3 = 3(5+ x) - 9(x + 1)
21 + 6x + 3 = 15 + 3x - 9x - 9
6x + 24 = 6 - 6x
12x = -18
x = -1.5
Answer:
x = -1.5.
Step-by-step explanation:
3(7 + 2x) + 3 = 3(5 + x) − 9(x + 1)
21 + 6x + 3 = 15 + 3x - 9x - 9
6x - 3x + 9x = 15 - 9 - 21 - 3
12x = -18
x = -18/12
x = -1.5.
