Why is x - y = 8 and y - x = c have many solution?

look at the picture.

y-intercept for the function on a picture is 4 → point (0, 4).

y-intercept for the function

is for x = 0. substitute:

y-intercept is 8 → point (0, 8).

6 adults and 9 children went.

a + c = 15

12a + 9c = 153

12(6) + 9(9) = 153

72 + 81 = 153

they share a side

step-by-step explanation:

this is the fundamental definition of adjacent angles

they:

1) share a vertex

2) share a side.
