Answer:
A
Step-by-step explanation:
When it's multiple choice, you can plug in each number until you find the correct answer. In this case: 9(-6)=3(-6)-36, which equals -54=-54. But, you can also solve for x without plugging in the numbers.
Steps:
1) 9x=3x-36
2) 6x=-36 Subtract 3x from both sides
3) x=-6 Divide both sides by 6
