A solution of an equation with two variables x and y is any ordered pair ( x,y) that makes the equation true.

3
Is (3,10) a solution of the equation y= 4x? y= 4x 10= 4 x 3 10≠12 so this is not a solution Substitute the value of the variables into he equation

4
Is (-2,3) a solution of the equation y= 2x +7? y= 2x+7 3=2 x -2 +7 3=3 so this is a solution Substitute the value of the variables into he equation
