simplify 8x-2y-x+5y

You have 8 apples(8x) and 5 oranges(5y), then take away one apple(-x) and 2 oranges(-2y).

What do you have ?

The answer would be 7x+3y.

The reason for this, is because you have to combine the "like" terms (8x goes with -x; -2y goes with 5y).

To simplify the expression 8x - 2y - x + 5y, you can combine like terms.

First, let's group the like terms together. In this expression, the x terms and the y terms are the like terms.

The x terms are 8x and -x. To combine them, you can subtract the coefficients: 8x - x equals 7x.

The y terms are -2y and 5y. To combine them, you can add the coefficients: -2y + 5y equals 3y.

Now, let's put the simplified x term and y term together: 7x + 3y.

Therefore, the simplified expression of 8x - 2y - x + 5y is 7x + 3y.
