Combine the x and y values:

3x-2x+5y+y=x+6y

3x + 5y - 2x + y

Okay first change the - sign to a + sign. And change the 2x to negative 2x.

3x + 5y + (-2x) + y

Now lets switch around the terms to make it easier.

3x + (-2x) + 5y + y

Now lets add them together!

3x + (-2x) = x
5y + y = 6y

So you're left with the problem..
6y + x

Now let's look at the second problem.
-7y + 8x + (-9x) - y

First, change the - sign to a + sign, and make the y negative.

-7y + 8x + (-9x) + (-y)

Now, lets switch around the numbers to make it easier.

-7y + (-y) + 8x + (-9x)

Now lets add them together!

-7y + (-y) = -8y
8x + (-9x) = -x

So you're answer is...
-8y + (-x)

I hope I helped you.

You can't solve it but you can simplify it by combining like terms. 3x-2x=x and 5y+y=6y. So if you simplify it you get 6y+x

-7y+8x+-9x-y
This one is -8y-x
The other one equals x+6y

You cannot solve it since you don't say what are the letter's value!

you cannot solve it as it has to be in an equation (an = some value)
