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

When $y = 0, x = 8, (x, y) = (8, 0)$

Step by step solution

Step 1. Given Informaion

Given equation is $x + 2 y = 8$

Step 2. Calculation

Since $x + 2 y = 8$

When $x = 0,$

Then $0 + 2 y = 8$

Therefore $y = 4$

Similarly

when $x = 4, y = 2$

Step 3. Calculation

Now when $y = 0,$ $y = 0,$

$x + 2.0 = 8$

Then $x = 8, y = 0$
