y = x
y = -x
x + y = 2
y = 3
x + 5y = 12
-x +y = 0
Find the value of two numbers if their sum is 12 and their difference is 4.
What is (8,4) ?
y = 3x - 4
y = -3x + 2
The solution to the system
2y - x = 4
10y - x = 20
-4x - 2y = -12
4x + 8y = -24

y = (1/3)x + 2
y = -x - 2
y = 6x - 11
-2x - 3y = -7
5x + y = 9
10x - 7y = -18
6x - 3y = -15
2x + y = -3

y = -1.5x - 4
y = 0.5x + 4
-3x + 3y = 4
-x + y = 3
-4x + 9y = 9
x = 3y - 6
