Exercise 32 Page 85

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

s=3.5

Practice makes perfect

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

17.5=5s
17.5/5=5s/5
3.5=s
s=3.5

Therefore, s=3.5 is the solution to the equation. To check that we have the correct solution, we can substitute s=3.5 into the original equation and simplify.

17.5=5s
17.5? =5* 3.5
17.5=17.5

Since the left-hand side and right-hand side are equal, s=3.5 is the correct solution.
