Solving Systems of Equations by Elimination Homework
Solve each of the following using the method of elimination:
1.
2x + y = 11
x+y=9
2.
x–y=7
2x + y = -10
3.
3x + y = 1
2x + 3y = -11
4.
x+y=1
3x – y = 11
5.
9x + 2y = 2
4x + y = 1
6.
2x + 3y = 8
5x – y = 3
7.
5x – 3y = -14
3x + 2y = 3
8.
9x + 6y = 12
8x + 3y = 13
9.
3x + 2y = 6
2x – 3y = 17
10.
2x + 5y = -2
5x – 2y = 24
11.
5x + 3y = 5
3x + 2y = 4
12.
2x + 8y = 24
x – 2y = 0
Find the error and rework the problem correctly.
