Chapter 1: Q. 23 (page 29)

In Problem 17-36, solve each equation algebraically. Verify your solution using a graphing utility.

5y+4y=3

Short Answer

Expert verified

The required solution is y=3and the graph of the solution is given below:

Step by step solution

01

Step 1. Given information.  

We have:

5y+4y=3

02

Step 2. Solve the equation algebraically.  

The equation is 5y+4y=3.

Multiply both sides by y:

5yy+4yy=3y5+4=3y9=3y

Switch sides:

3y=9

Multiply both sides by 3:

3y3=93y=3

03

Step 3. Verify the solution using a graphing utility.  

The solution of the equation isy=3.

Draw the graph of the equation 5y+4y=3using the graphing utility:
