- We know the values we can substitute for x & y
x=2,5,8,9
y=3,4,6,8
In the equation 6x+15y we substitute the value of y and try to find x,
if we substitute y as 6&8 it exceeds the values in the Options.
If y=4, then we can check value from options by changing values of x we have, ut we will not get answers in the options.
If y=3 and if take x=5 we get 75 which is Option B.
