SOLVING SYTEMS OF LINEAR EQUATIONS PRACTICE PROBLEMS

Solve these simultaneous equations.

Problem 1 :

4x + y = 8

x + y = 5

Problem 2 :

3x + y = 7

3x + 2y = 5

Problem 3 :

4x + y = 3

3x - y = 11

Problem 4 :

3x + 4y = 7

x - 4y = 5

Problem 5 :

2x + y = 11

x - 3y = 9

Problem 6 :

2x + 3y = 11

3x + 2y = 4

Answer Key

1) Solution is x = 1 and y = 4.

2) Solution is x = 3 and y = -2.

3) Solution is x = 2 and y = -5.

4) Solution is x = 3 and y = -1/2.

5) Solution is x = 6 and y = -1.

6) Solution is x = -2 and y = 5.

7) Solution is x = 7 and y = -3.
