Question

Use elimination to solve each system below.

System 1
2x + 3y = 6
- 2x - y = – 6
System 2
2x + 3y = 6
x + y = 4
Enter the values of x and y in the solution for each system in the following table.
value of x
value of y
System 1 1
System 2

Answer 1

System 1 : {3,0}; System 2 : {6,-2}

Explanation:

2x + 3y = 6

-2x - y = -6

2y = 0

y = 0

-2x = -6

x = 3

system 2

2x + 3y = 6

2x + 2y = 8

y = -2

2x -4 = 8

2x = 12

x = 6
