- Equation 1: 2x + y = 7
- Equation 2: 3x - y = 8
Add the two equations to eliminate the ys:
- 2x + y = 7
- 3x - y = 8
- ------------
- 5x = 15
- x = 3
- Now you can put x = 3 in either of the equations.
- Substitute x = 3 into the equation 2x + y = 7:
- 6 + y = 7
- y = 1
So the answers are x = 3 and y = 1
