$(5, 8)$ , $4 x + y = 7$

Step 1

Insert the values of $x = 5$ and $y = 8$ into the equation to find if the ordered pair is a solution.

$4 (5) + 8 = 7$

Step 2

Simplify $4 (5) + 8$ .

Step 2.1

Multiply $4$ by $5$ .

$20 + 8 = 7$

Step 2.2

Add $20$ and $8$ .

$28 = 7$

Step 3

Since $28 \neq 7$ , there are no solutions.

No solution

Step 4

Since the equation is not true when the values are used, the ordered pair is not a solution.

The ordered pair is not a solution to the equation.
