Solve the system of equations and choose the correct ordered pair.
2 answers:
4x + 5y = 22 ⇒ Equation 1
2x + 3y = 12 ⇒ Equation 2
2(2x + 3y) = 2(12)
4x + 6y = 24 ⇒ Equation 3
Equation 1 - 3
(4x - 4x) + (5y - 6y) = 22 - 24
-y = -2
y = 2
Substitude y into Equation 1,
4x + 5(2) = 22
4x + 10 = 22
4x = 12
x = 3
