Question

Graph the following system of equations:

2x + 3y = -6
x - 3y = 15
what is the solution to this system?

Answer 1

x = 3

y = -4

Explanation:

see attached

the solution to the system of equations correspond to the coordinates of the point of intersection of the 2 graphs.

turns out that the graphs intersect at (3,-4)

hence the solution is x = 3 and y = -4
