Use the elimination method to solve the system of equations. Choose the correct ordered pair.7x + 4y = 392x + 4y = 14A.(5, 1)B.(5, 4)C.(3, 4)D.(3, 2)
Question
Solution 1
To solve the system of equations using the elimination method, follow these steps:
Align the equations:
7x + 4y = 39 2x + 4y = 14
Subtract the second equation from the first to eliminate y:
(7x + 4y) - (2x + 4y) = 39 - 14 5x = 25
Solve for x:
x = 25 / 5 x = 5
