phi · Answer

(5, ?)  is an (x,y) pair
here they are saying x is 5, and want you to find y.  to find y, use
y=20-2x

erase the x, and write in 5 instead. then do the arithmetic.  
can you do that ?

Think about how can you will in y with x?

anonymous · Answer

Solve the equation by filling x with 5. The answer is Y
