Question

2x - 2y = 6
3x + 2y = 9


Solve the system of equations.
A)
x = 0, y = 3
B)
x = 3, y = 0
C)
x = 1, y = -2
D)
x = -2, y = 1

Answer 1

since you have -2 and +2 for the y values you can just combine both equations and eliminate the y combining the x's you have 5x combining the y's you have 0 and combining the constants you have 15 so you are left with 5x=15 can you solve this?
