Answer:
A. (4, 12)
Step-by-step explanation:
Adding the second equation to twice the first will eliminate y.
2(10x +2y) +(3x -4y) = 2(64) +(-36)
23x = 92 . . . . . . . . simplify
x = 4 . . . . . . . . . divide by 23
This value matches choice A: (4, 12).
We have been given that the Walters bought a house and calculated they would pay 28% of their combined income of $5436.68 toward their monthly mortgage payment on the house.
To find the amount of monthly mortgage payment, we will find 28% of combined income.
Therefore, the Walters will pay approximately for their monthly mortgage payment.
