Select the ordered pair from the choices below that is a solution to the following system of equations:
4y = x - 13
2x + 16y = 20
Answered by Henry
Write 1st Eq in STD form:
x - 4y = 13
2x + 16y = 20
Multiply 1st Eq by -2:
-2x + 8y = -26
2x + 16y = 20
Add the 2 Eq:
24y = -6
y = -1/4
Substitute -1/4 for y in the 1st Eq
and solve for x:
x - 4(-1/4) 13
x = 12.

(12 , -1/4).
