Question

solving each inequality and graphing the solution:i) 3x + 1 < 10ii) -2y + 22 < 10

Answer 1

Given:

3x + 1 < 10

Solve:

Subtract 1 from both sides:

3x + 1 - 1 < 10 - 1

3x < 9

Divide both sides by 3:

$\begin{gathered} \frac{3x}{3}<\frac{9}{3} \\ \\ x<3 \end{gathered}$

Graph x<3:

ii) -2y + 22 < 10

SUbtract 22 from both sides:
