# Quantitative method for solving equations

Solve the following equations and find the values of x and y.

2x + y = 4

4x - 2y = 24

Please graph the equation, choose your own range, but make sure the two graphs intersect.

#### Solution Preview

First solve each equation for y:

1) 2x + y = 4

subtracting 2x from both sides of the equation yields:

y = 4 - 2x

2) 4x - 2y = 24

subtracting 4x from both sides of the equation yields:

-2y = 24 - 4x

dividing -2 into both sides of the equation and rearranging ...

#### Solution Summary

This solution helps solve the missing variables for various equations. That equations are graphed and places where the graphs are intersected are found.
