Solve each system of equations using the elimination method. Show all your work.
1. Solve the system:
x + y = 7
x - y = 3
2. Solve the system:
2x + 3y = 11
x - 2y = 2
3. Solve the system:
3x - 5y = -1
-2x + 4y = 2
4. Which system of equations would require multiplying both equations to eliminate a variable?
x + y = 5 x - y = 1
2x + y = 7 3x - y = 3
4x + 2y = 10 6x + 3y = 15
5x - 2y = 8 5x + 3y = 18
5. When using the elimination method, the goal is to make the coefficients of one variable opposites so they cancel out when the equations are added.
True
False
6. To eliminate the 'y' variable in the system: 3x + 2y = 10 5x - y = 3 you would multiply the second equation by .
