Answer:
(0, 2)
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.
