There's nothing to solve here. You just have two expressions.

Did you intend to write two equations? Please show the entire problem you are trying to solve.

He is right It's just an equation not a question, so please check again and write a question?

That's better, but still not enough. Were you told that the two triangles are congruent, for example? We need some information to tell us how the quantities are related.

If they are congruent, then you can write two equations, and solve each of them (separately). Do you see what they will be?

The picture shows two facts:

13x-9 = 17
7y-4 = 80

Do you see why?
