Question

Find two solutions to the linear equation x = 15 − y.

Answer 1

Explanation:

hello :

if y=0 so x= 15 and if : x=0 so y = 15

you have two solutions : (15;0) and (0;15)

Answer 2

(-1, 16), (3, 12)

These are my examples so if you want you can do different solutions, too!

Explanation:

It may sound weird, but there are infinitely many solutions to a linear equation. It's basically all real numbers that are on the line.

So, just choose two random numbers for the x-value and substitute in into the equation. I'm going to use -1 and 3.

x = 15 - y

when x = -1

-1 = 15 - y

y = 16

(-1, 16)

when x = 3

3 = 15 - y

y = 12

(3, 12)
