Question

Solve the problem by graphing 4x-2y=22 6x+9y=-3

Answer 1

Change these equations into the equations of linear functions.
$\left \{ {{4x-2y=22} \atop {6x+9y=-3}} \right. \\ \\ \left \{ {{-2y=-4x+22} \atop {9y=-6x-3}} \right. \\ \\ \left \{ {{y=2x-11} \atop {y=-\frac{2}{3}x-\frac{1}{3}}} \right.$

Draw function graphs and read coordinates of the intersection.
$\left \{ {{x=4} \atop {y=-3}} \right.$
