Use the substitution method to solve the system of equations Enter your answer as an ordered pair y equals x - 7 x plus y equals 5?

y = x - 7

x + y = 5

Substituting for y in the second equation,

x + (x - 7) = 5

or 2x = 12 so that x = 6

Then, from the first equation, y = 6 - 7 = -1

So, (x, y) = (6, -1)
