Answer:

(0, 2)

Step-by-step explanation:

12.5x + 2.5y = 5

y = 5x + 2

12.5x + 2.5(5x + 2) = 5

12.5x + 12.5x + 5 = 5 (distribution property)

25x = 0 (combined like terms)

x= 0

y = 5(0) + 2

y = 2

check

12.5(0) + 2.5(2) = 5

5 = 5

Yes

B)

I would use the first equation (y = 5x + 2) to substitute into the second equation (12.5x + 2.5y = 5) because it is already (y = ...) so it is easier to insert it into the second equation.
