Question

What would this question be?

Answer 1

X + Y = 9

X - Y = -5

Explanation:

X + Y = 9

X - Y = -5

To solve these equations add these

X + Y + X - Y = 9-5

2X = 4

X =2

Now substitute X = 2 in any of those top equations.

`x + y = 9 \\ 2 + y = 9 \\ y = 9 - 2 \\ y = 7`

Answer 2

Answer (by problem steps on your screen):

x + y = 9

x - y = 5

x = 2

y = 7

Explanation:

X is not known, condition of first equation is x + y = 9 and second be x - y = 5. Both together is x = 2 and y = 7

Hope this helps you! (no seriously, I hope it does)
