Answer:
x = 5
y = -4/3
Step-by-step explanation:
Solve by elimination by adding the two equations together:
2x + 3y = 6
x – 3y = 9
3y and -3y will cancel out. Then, solve for x:
3x = 15
x = 5
Plug in 5 as x into one of the equations, then solve for x:
x – 3y = 9
5 – 3y = 9
-3y = 4
y = -4/3
So, the answer is x = 5 and y = -4/3
