Answer:
w = 7.25
Step-by-step explanation:
w + 1.5 = 8.75
To find what w is, you need to isolate. To isolate w from 1.5, you have to subtract 1.5 by 1.5.
w + 1.5-1.5 = 8.75
What you do to one side of the equal sign, you have to do to the other
w + 1.5-1.5 = 8.75 - 1.5
1.5-1.5 cancels out and 8.75 - 1.5 equals to 7.25
w = 7.25
