Answer:
A
Step-by-step explanation:
x+y=7
x-y=3
Firstly get x on its own.
You do this by adding the equations together. -y + y=0 (ethey cancel out but x+x=2x and 7+3=10
from this it shows us 2x=10
Now het x on its own by dividing by 2
this leaves us with x=5
Now input this into any of the two equations and you will get y.
For example,
5+y=7
7-5=y
y=2
input this into the equations (x,y)
which leaves us with...
(5,2)
