Answer 1

Answer:

the correct answer is a

Step-by-step explanation:

Answer 2

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)
