#-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"#
