Step by Step Solution

Step 1. Given Information 

In the given question we have to solve the inequality: 3-2x>5and graph the solution set.

Step 2. The given inequality is 3-2x>5

Now solving the equation.

Subtract 3 on both side

3-2x-3>5-3

Simplify

-2x>2

Step 3. Divide by -2 and replace the inequality.

-2-2x<2-2x<-1

The solution set is {x|x<-1} and interval notation is (-,-1]

Step 4. The interval notation is (-∞,-1]

The graph is
