Answer:
Explanation:
We can see both equations have same variable 3x, one with positive and one with negative coefficient. If we add up the equations they will cancel, thus the variable x is eliminated.
Add up the equations and solve for y:
- y + 3x + 2y - 3x = -2 + 14
- 3y = 12
- y = 12/3
- y = 4
Now solve for x:
- 4 + 3x = -2
- 3x = -2 - 4
- 3x = -6
- x = -6/3
- x = -2
