How to simplify

6x+5y-2x-9x+3y

You can simplify this expression by putting all of the coefficients with the same variables next to each other.

6x - 2x - 9x + 5y + 3y

Then, combine the ones that have the same variables. Add (or subtract) the numbers like normal.

6x - 2x - 9x + 5y + 3y

4x - 9x + 5y + 3y

-5x + 5y + 3y

-5x + 8y

Take all the variables and put them next to each other but still in order.

Keep their negatives and positives.

6x-2x-9x 5y+3y

Do the math with the variables that way, and you'll get an answer of

-5x 8y

Reform them into the simplified equation, so you'll end up with an equation of

-5x+8y

The x would be before the y since that's how it is in the alphabet. That would be a simplified form of the equation.
