Given
Required
x and y
Add both equations to eliminate y
Divide both sides by 6
Substitute in the first equation
Divide by -3
3x + 2y = 17
4x - 2y = 4
7x = 21
7 7
x = 3
3(3) + 2y = 17
9 + 2y = 17
- 9 - 9
2y = 8
2 2
y = 4
(x, y) = (3, 4)
4x - 2y = 4
7x = 21
7 7
x = 3
3(3) + 2y = 17
9 + 2y = 17
- 9 - 9
2y = 8
2 2
y = 4
(x, y) = (3, 4)
