64*x+16y-5*x+84

There is no equal sign, there is nothing to find out.

64*x+16*y-5*x+84=

forgot it sry

how about now

Saying so and so = [does not insert value here]

is not very useful to solving.

It makes no difference.

There cannot be a solution unless something = something

This is an EXPRESSION with TWO unknowns

to solve for x and y you will need TWO EQUATIONS relating x and y

somethinig (this is just an example) like:

32x + 54y - 4*x+ 84 = 88 AND x+2y = 17

let's say its like yours how to solve it

I am sorry guest but you simply have not asked a question.

EP and all of us, are just trying to explain that to you.
