Exercise 18 Page 190

Start by distributing the negative, and then simplify the terms.

c<2

Practice makes perfect

We solve inequalities similarly to how we solve equations. We can distribute the negative sign and then simplify the terms in order to isolate c.

- (7c-18)-2c>0
- 7c+18-2c>0
- 9c+18>0
18>9c
18/9>c
2>c
c<2

The solution to the inequality is c<2.
