Answer:
-2
Step-by-step explanation:
1. Rewrite the equation:
2(3x - 3) = -18
2. Use the distributive property:
2(3x - 3) = -18 ---> 6x - 6 = -18
3. Add 6 to both sides:
6x - 6 = -18 ---> 6x = -12
4. Divide both sides by 6:
6x = -12 ---> x = -2
Now we know our answer is -2, let's make sure it's correct:
2(3x - 3) = -18
2(3(-2) - 3) = -18
2(-6 - 3) = -18
-12 - 6 = -18
-18 = -18
This tells us our answer is true!
Hope this helps :D
