Use the substitution method to solve the system of equations. choose the correct ordered pair.

B.      (6,3)

Step-by-step explanation:

14x - 2y = 78

2x - 2y = 6

-2y/-2 = (6 - 2x)/-2

y = -3 + x

substitute this y in for the y of the first equation

14x - 2(-3+x) = 78

14x + 6 - 2x = 78

12x + 6 = 78

12x = 72: x = 6

use x to plug into 2nd equation to make life easier

y = -3 + (6)

y = 3
