Answer:
w=-1
Step-by-step explanation:
3w-7w-12=2(w-3)
1) Combine alike terms:
-4w-12=2(w-3)
2) Use the Distributive property on the left side of the equation:
-4w+12=2w-6
3) Add a 6 to both sides:
-4w-6=2w
4) Add a 4w to both sides:
-6=6w
5) Divide both sides by 6:
w=-6/6
6) Simplify the fraction:
w=-1
