Exercise 25 Page 190

Use inverse operations to isolate f.

f≤ 6

Practice makes perfect

We can solve inequalities in almost the same way as equations. The only difference is that we need to remember to flip the inequality sign when multiplying or dividing by a negative value.

5f+8≥2+6f

LHS-5f≥RHS-5f

8≥2+f

LHS-2≥RHS-2

6≥ f

Rearrange inequality

f≤ 6

The solution to the inequality is f≤ 6.
