# How do you solve the system by graphing 4x - 2y = -12 and 2x + y = -2?

Jul 13, 2017

$x = - 2$, $y = 2$

#### Explanation:

To solve $x$ and $y$ in $2$ or more functions, you are actually finding $x$ and $y$ values which satisfy all the functions.

In other words, you are finding the intersections of the functions since at intersections, the functions are having the same value for $x$ and $y$

In this case, I have plotted the functions on the same plane.

The intersection point (in this case only $1$) has the coordinate (-2,2)

$\therefore$ $x = - 2$, $y = 2$

graph{(4x-2y+12)(2x+y+2)=0 [-7.9, 7.9, -3.94, 3.96]}
