Solve using substitution y = 4 and - 4x - 3y = 12 Give the answer as an ordered pair.

(-6,4)

Step-by-step explanation:

since (y) is already solved, you would substitute the y in the second equation so:

y=4 and - 4x-3y=12

-4x-3 (4) = 12 (Distribute)

-4x-12=12.

(add 12 to both sides to remove the constant)

-4x=24

(divide both sides by the coefficient so - 4)

x=-6

now write it as an ordered pair (x, y) : (-6,4)
