Answer: x=5

b=6

v=3

Step-by-step explanation: so what you want is to get the variable on one side of the =. So that means you have to cancel out the number next to the variable to isolate the variable. so for the first problem ,x+2=7 you will subtract 2 from 2 and subtract 2 from 7 which equals 5. for the next problem you will add 5 to both sides, the last problem divide by 4 on both sides.

Answer:

1: x=5

2: b=6

3= V=3
