Solve the system of equations by substitution.

x+y=12
y=5x
(type an ordered pair)

Substituting the second equation into the first equation, we get:

x + 5x = 12
6x = 12
x = 2

Substituting x = 2 into the second equation, we get:

y = 5(2)
y = 10

Therefore, the solution to the system of equations is (2, 10).
