Answer:
Step-by-step explanation:
x + 3y = 15 ×4
4x + 2y = 30 ×1
4x + 12y = 60
- - -
4x + 2y = 30
10y = 30
y = 30/10
y = 3
To solve for x, substitute y = 3 into any of the equations
x + 3(3) = 15
x + 9 = 15
x = 15 - 9
x = 6
(6,3)
This should be the answer but I don't see that in the options u listed, so I don't know what else it should be.
