When using substitution to solve this system of equations, what is the result of the first step? x = 6y + 3,x + 2y = 5

Question

A.x + 2y + 6y = 3 + 5

B.x + 2 (6y + 3) = 5

C.(6y + 3) + 2y = 5

D.none of these

Answer 1

C is corredt

x = 4.5

y = 0.25

plug those values into the original equations, they work

plug those into A or B's equations, they don't work.
