Two equations and their graphs are given. Find the intersection point(s) of the graphs by solving the system.

multiply x- 3y = -5

x= 3y -5

substituting in the other equation

2x + y = -3

2(3y -5) + y = -3

6y -10 + y = -3

7y = 7

y=1................................

put this value in x= 3y -5

x= 3- 5

= -2.......................

ANSWERS ARE x = -2

y = 1
