Chapter 4: Q 30. (page 430)

In the following exercises, complete the table to find solutions to each linear equation.

Short Answer

Expert verified

When x=0,y=4,(x,y)=(0,4)

When x=4,y=2,(x,y)=(4,2)

Wheny=0,x=8,(x,y)=(8,0)

Step by step solution

01

Step 1. Given Informaion

Given equation isx+2y=8

02

Step 2. Calculation 

Since x+2y=8

When x=0,

Then 0+2y=8

Therefore y=4

Similarly

whenx=4,y=2

03

Step 3. Calculation 

Now when y=0,y=0,

x+2.0=8

Thenx=8,y=0
