Extraneous root since dividing by zero is undefined
Y = 4x - 3
y = mx + b
m = 4
b = -3
y intercept = (0,3)
(x,y) = (0,3)
(x,y) = (1,1) - substitute in ori equation
Answer:
x - 9
Step-by-step explanation:
Answer:
x = 2 and y = -2
Step-by-step explanation:
We must first eliminate the y-variable:
2x + 3y = -2
3x - 6y = 18
4x + 6y = -4
3x - 6y = 18
_________
7x = 14
x = 2
Since we know x=2, we plug that back into one of the original equations to find y:
2x + 3y = -2
2(2) + 3y = -2
4 + 3y = -2
3y = -6
y = -2
Therefore, x = 2 and y = -2
Answer:
y = -1
