Hi Brainiac
y=3x-7
y=2x+1
We need to solve y=3x-7 for y
Now let's start by substitute 3x-7 for y in y=2x+1
y=2x+1
3x-7=2x=1
Now add -2x
3x-7-2x=2x+1-2x
x-7=1
Add 7
x-7+7=1+7
x=8
Our last step is to substitute 8 for x in y=3x-7
y=3x-7
y=(3)(8)-7
y= 24-7
y= 17
Answer : A
I hope that's help:)

Answer:
9. -6x+10
10. -24x +18y
11. 15y - 10z
12. -8x- 28
13. -7x + 14
14. -24x +12

Answer:
(0, 7), (1, 11), (2, 15)
Step-by-step explanation:
to find the y values, plug in the given x values into the equation y= 4x+7
when x = 0
y = 4(0) + 7
y = 0 + 7
y = 7
so the y value that corresponds to the x value 0 is 7 which is also written as (0,7)
when x = 1
y = 4(1) + 7
y = 4 + 7
y = 11
so the y value that corresponds to the x value 1 is 11; also written as (1, 11)
when x = 2
y = 4(2) + 7
y = 8 + 7
y = 15
so the x value 2 corresponds to the y value 15; also written as (2 , 15)
