Answer:
The correct one is A
Step-by-step explanation:
2x-y=10
y=1/2 × x+5
Now you substitute the value of y into the first equation.
2x - (1/2 × x+5) = 10
Solving this equation for x you get that x=6
Now substitute the value of x any of these two equations, doesn't matter. Let's say we do with the first one.
2×6-y=10
12-y=10
-y=10-12
-y= -2
y=2
And so you've got the first one which is, (x,y)=(6,2)
