Hey Gaurav, here is a small thing process-wise. When you write down stuff, the first thing you should write down is key. What are you assuming x and y to be? To me, it looks like you're taking x and y to be moles, correct? Okay. Now, in your solution, I feel you should also write units everywhere. Simple things like moles is what? Moles into molar mass will give you grams, which is what you've done in the first expression. In the second expression though, and number your points, like this is the first expression, the second expression. Second expression is 7x plus y is equal to 320, I think that's off, because it should be 7x plus y into 32 is equal to 320, because there also x and y are still moles, whereas 320 is mass. You see where things are off?

thanks sir i will retry after getting free

and yes i will add numbers to equations and also use proper units
