Question

What is the solution for the system? Use the graph below

y-x=-3 (line a)
y+x=3 (line b)

A. (0,3)
B. (-3,0)
C. (0,-3)
D. (3,0)

Answer 1

If you would like to know what is the solution for the system of equations, you can calculate this using the following steps:

y - x = - 3
y + x = 3
_______________
y - x + y + x = - 3 + 3
2y = 0
y = 0

y - x = - 3
0 - x = - 3
x = 3

(x, y) = (3, 0)

The correct result would be D. (3, 0).
