Exercise 18 Page 85

How can you isolate c on the left-hand side?

c=-13

Practice makes perfect

To solve the equation we need to isolate c on one side of the equation. By subtracting 4 from both sides, we can cancel it from the left-hand side.

c+4=-9
c+4-4=-9-4
c=-13

Therefore, c=-13 is the solution to the equation. To check that we have the correct solution, we can substitute c=-13 into the original equation and simplify.

c+4=-9
-13+4? =-9
-9=-9

Since the left-hand side and right-hand side are equal, c=-13 is the correct solution.
