Find Three Ordered Pair Solutions x+y=8

$x + y = 8$

Step 1

Subtract $x$ from both sides of the equation.

$y = 8 - x$

Step 2

Choose any value for $x$ that is in the domain to plug into the equation.

Step 3

Choose $0$ to substitute in for $x$ to find the ordered pair.

Remove parentheses.

$y = 8 - (0)$

Subtract $0$ from $8$ .

$y = 8$

Use the $x$ and $y$ values to form the ordered pair.

$(0, 8)$

Step 4

Choose $1$ to substitute in for $x$ to find the ordered pair.

Remove parentheses.

$y = 8 - (1)$

Simplify $8 - (1)$ .

Multiply $- 1$ by $1$ .

$y = 8 - 1$

Subtract $1$ from $8$ .

$y = 7$

Use the $x$ and $y$ values to form the ordered pair.

$(1, 7)$

Step 5

Choose $2$ to substitute in for $x$ to find the ordered pair.

Remove parentheses.

$y = 8 - (2)$

Simplify $8 - (2)$ .

Multiply $- 1$ by $2$ .

$y = 8 - 2$

Subtract $2$ from $8$ .

$y = 6$

Use the $x$ and $y$ values to form the ordered pair.

$(2, 6)$

Step 6

These are three possible solutions to the equation.

$(0, 8), (1, 7), (2, 6)$
