$- 12, 3), (3, 0) and (- 22, 5)$ $-12,3), (3,0)" and " (-22,5)$

Explanation:

To determine which of the ordered pairs are solutions to the given equation.

Substitute the x and y coordinate of each pair into the equation and if equal to 3 then the pair is a solution.

$∙ (- 12, 3) \to - 12 + (5 \times 3)$ $• (-12,3)to-12+(5xx3)$

$= - 12 + 15 = 3 \leftarrow solution$ $=-12+15=3larrcolor(red)" solution"$

$∙ (3, 0) \to 3 + (5 \times 0)$ $• (3,0)to3+(5xx0)$

$= 3 + 0 = 3 \leftarrow solution$ $=3+0=3larrcolor(red)" solution"$

$∙ (- 12, - 3) \to - 12 + (5 \times - 3)$ $• (-12,-3)to-12+(5xx-3)$

$= - 12 - 15 \neq 3 \leftarrow not a solution$ $=-12-15!=3larrcolor(blue)" not a solution"$

$∙ (- 22, 5) \to - 22 + (5 \times 5)$ $• (-22,5)to-22+(5xx5)$

$= - 22 + 25 = 3 \leftarrow solution$ $=-22+25=3larrcolor(red)" solution"$
