Question

Solve the system of equations:
2x+y=12
3x-y=3
show work pls

Answer 1

x = 3; y = 6

Explanation:

Using elimination method:

2x + y = 12

+. (the y will cancel out)

3x - y = 3

5x = 15

therefore, x = 15

5

x = 3

substitute x in one of the equations

2(3) + y = 12

6 + y = 12

y = 12 - 6

y = 6

therefore y = 6
