Question

X + y = 12 x - y = 2

Answer 1

x = 7

y = 5

(7, 5)

Explanation:

From the way, this question looks I'm going to assume substitution.

x + y = 12

x - y = 2

------------------

2x = 14

÷2 ÷2

-------------

x = 7

x + y = 12

7 + y = 12

-7 -7

-------------------

y = 5

I hope this helps!
