Chapter 1: Q. 23 (page 29)

In Problem 17-36, solve each equation algebraically. Verify your solution using a graphing utility.
$\frac{5}{y} + \frac{4}{y} = 3$

Short Answer

Expert verified

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

Step by step solution

Step 1. Given information.

We have:

$\frac{5}{y} + \frac{4}{y} = 3$

Step 2. Solve the equation algebraically.

The equation is $\frac{5}{y} + \frac{4}{y} = 3$ .

Multiply both sides by $y :$

$\frac{5}{y} y + \frac{4}{y} y = 3 y 5 + 4 = 3 y 9 = 3 y$

Switch sides:

$3 y = 9$

Multiply both sides by $3 :$

$\frac{3 y}{3} = \frac{9}{3} y = 3$

Step 3. Verify the solution using a graphing utility.

The solution of the equation is $y = 3 .$

Draw the graph of the equation $\frac{5}{y} + \frac{4}{y} = 3$ using the graphing utility:
