7(4 + 3x) = 45(x - 3) - 3(2x - 12)
Distribute:
28 + 21x = 45x - 135 - 6x + 36
Collect like terms:
28 + 21x = 39x - 99
Rearrange terms to get them all on one side (add 99 to both sides):
28 + 99 + 21x = 39x - 99 + 99
Simplify:
127 + 21x = 39x
Subtract 21x from both sides:
127 + 21x - 21x = 39x - 21x
127 = 18x
Divide by 18 on both sides to isolate the x variable and solve the expression:
127/18 = 18x/18
x = 127/18
