how do you solve 9x+8y=11 for x and y

You need two independent equations to get unique values for x and y.

the problem asks if (1,6) is a solution to this equation and this is all it gives me

Well that is a help!
(1,6)
and
9x+8y=11 for x and y
well now
9(1) +8(6) = 11 ? or not?
9  48 = 11 ? NO WAY
