Answer: W= 0.5

Step-by-step explanation:

You add 3w to both sides to get -5= 10w and then you divide everything by 10 to get w= 0.5

-5 - 3w = 7w

-5 - 3w+3w = 7w+3w <<--- add 3w to both sides

-5 + 0w = 10w

-5+0 = 10w

-5 = 10w

10w = -5

10w/10 = -5/10 <<--- divide both sides by 10 to isolate w

w = -5/10

w = -1/2 <<--- reduce; this is the answer in fraction form

w = -0.5 <<---  this is the answer in decimal form
