13%, 5 years, 2500 could most likely maybe be the answer a question
Multiply the second equation by 3
-4x+9y=9
3x-9y=-18
add the equations together
-x=-9 Simplify
x=9
now plug in your x value
(9)-3y=-6 Simplify
-3y=-6-9
-3y=-15
y=5
40 because the three in the units place is smaller than 5 so you round down.
I would say the answer is 4 and 6, if you are allowed to choose more than one answer. If not, I would choose 4
