5-78.

Solve each inequality like you would solve any equation.

Solve for the variable by isolating the variables and number values.

3*x* − 4 < 3 − 2*x*

+ 2*x* + 2 *x*

Note: Steps 1 and 2 can happen in any order.

5*x* − 4 < 3

+4 +4

5*x* + 0 < 7

Simplify.

5*x* < 7

Use this simplified inequality to create a number line similar to problem 4-68.

Now try part (b) using the same strategy.
