Question

Solve the following system of equations:

x -2y = 18
4x + 3y = -16
What's the (x,y) coordinates

Answer 1

Explanation:

Solve for X for one equation then input that value into the other equation.

x+2y=9

x=9-2y

x-y=3

(9-2y)-y=3

9-3y=3

6=3y

y=2

x=5

The value of the y-coordinate of the system of equations is y=2.

I hope it help
