Answer:
7/5
Step-by-step explanation:
Isolate x
12x-15=6-3x
12x-15+15=6-3x+15 (add fifteen, addition property of equality)
12x=6-3x+15
12x=21-3x (combine like terms)
12x+3x=21-3x+3x (add 3x, addition property of equality)
15x=21 (combine like terms)
15x/15=21/15 (divide by 15, division property of equality)
x=7/5 (simplify)
