Exercise 12 Page 85

How can you isolate v on the right-hand side?

v=18

Practice makes perfect

To solve the equation we need to isolate v on one side of the equation. By subtracting 5 from both sides, we can cancel it from the right-hand side.

23=v+5
23-5=v+5-5
18=v
v=18

Therefore, v=18 is the solution to the equation. To check that we have the correct solution, we can substitute v=18 into the original equation and simplify.

23=v+5
23 ? =18+5
23=23

Since the left-hand side and right-hand side are equal, v=18 is a correct solution.
