Hey I'm a little confused because 12-12=0, and x can't be 0. Can someone show me this problem?

✔ 最佳答案

6(2x + 1) - 3(4x - 3) = 3
6(2x) + 6(1) - 3(4x) + 3(3) = 3
12x + 6 - 12x + 9 = 3
12x - 12x = 3 - 6 - 9
0 = -12
(no solution)

6(2x+1)-3(4x-3)=3
12x + 6 - 12x + 9 = 3
15 = 9
This is not possible. Therefore the equation has no solution.
