Systems of Equations
Use substitution to solve the following system of equations.
y = 2x - 1
2x + 3y = 5
x + 4y = 5
2y - x = 7
y + 2 = 4x
3y + 2x = 1
Use elimination to solve the following systems.
x + 3y = 5
- x - 7y = 3
- 2x + y = 1
4x + 3y = 8
2x + 3y = 7
x + 5y = 4
7x + 6y = 8
5x + 4y = 6
Solve the following systems by any method.
x = 3y - 2
3x - 5y = 10
x - 2y = 0
6x - 13y = 5
