Starts With S
y = x + 4
y = 2x + 5
r + s = -6
r - s = -10
x = 4y
2x + 3y = 22
y = 3x - 2
y = -x - 2
8a + 5b = 9
2a - 5b = -4
y = x - 2
3x - y = 16
y = -3
x = 5
The solution to the system:
-10x -15y =-30
9x + 15y = 45
What is (-15, 12)?
y = 3x - 1
7x + 2y = 37
y = (1/3)x - 3
2x - y = 8
The solution to the system
8a - 16b =48
-8a + 16b = -48
What is infinitely many solutions?
3s - 2t = 4
t = 2s - 1
y - 3x = 3
y = 3x - 2
(1/3)x + (1/4)y = 10
(1/3)x - (1/2)y = 4
t + u = 12
t = (1/3)u
