answer the question then graph:
1. x – 2y = 4 2x + y = 1 if x= 0. what is the value of y? If y= 0. what is the value of x? 0
2. Y = X + 7 Y = X – 4 if x= 0. what is the value of y? If y= 0. what is the value of x?
3. 2x + y = 3 4x + 2y = 6 if x= 0. what is the value of y? If y= 0. what is the value of x?

Answer:
1. x = 4
x = 1/2
y= 2
y = 1
2. x = -7
x=4
y=7
y=-4
3. x=2/3
x=3/2
y=3
y= 3
Step-by-step explanation:
1. x -2(0)=4. 0 - 2y=4
x-0=4. -2y=4-0
x=0+4. -2y=4
x=4. y=-2
2x + (0) = 1. 2(0) + y = 1
2x = 1-0. 0 + y = 1
2x=1. y = 1-0
x= 1/2. y = 1
