Answer:
All real numbers
Step-by-step explanation:
-3(4-3x)=9x -12
-12+9x=9x-12
-12+12=9x-9x
0=0
In this case since both sides are zero, x would be all real numbers because that means any number can satisfy the solution without it being false.
For instance -1, both sides would still be -21
And for 2, both sides would be 6
