Question

Which of the ordered pairs (–12, 3), (3, 0), (–12, –3), (–22, 5) are solutions for the equation x + 5y = 3?

Answer 1

`-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+(5xx3)`

`=-12+15=3larrcolor(red)" solution"`

`• (3,0)to3+(5xx0)`

`=3+0=3larrcolor(red)" solution"`

`• (-12,-3)to-12+(5xx-3)`

`=-12-15!=3larrcolor(blue)" not a solution"`

`• (-22,5)to-22+(5xx5)`

`=-22+25=3larrcolor(red)" solution"`
