Directions- Solve the system of equations.
1. 2x – 3y = -13
y = 4x + 1 Video:
2. –x + 2y = 8
x = y – 5
3. 3x – 2y = 7
x = -2y + 1
4. y = 4x + 1
y = 2x – 7
5. 2x – 6y = 7
x = 3y + 5
6. 2x – 3y = -13
5x + y = -7
7. x + y = 6
x + 3y = 10
8. 2x + 3y = 7
x + y = 4
9. 3x – y = 3
2x + y = 7 Video :
10. 4x + 3y = 15
2x – 5y = -25
