simplify 7x-10x+8+9-9x

To simplify the expression 7x - 10x + 8 + 9 - 9x, we can combine like terms.

Combining the x terms, we have:
7x - 10x - 9x = -12x

Combining the constants, we have:
8 + 9 = 17

Therefore, the simplified expression is:
-12x + 17

To simplify the expression 7x - 10x + 8 + 9 - 9x, we can combine like terms:

First, let's combine the "x" terms: 7x - 10x - 9x
Combining these terms, we get: -12x

Next, let's combine the constants: 8 + 9
Adding these constants, we get: 17

Putting it all together, the simplified expression is: -12x + 17

To simplify the expression 7x - 10x + 8 + 9 - 9x, we combine like terms. Like terms are terms that have the same variable raised to the same power.

First, let's group the terms with x together:
7x - 10x - 9x

To combine these terms, we add or subtract their coefficients. In this case, 7x - 10x - 9x simplifies to -12x.

Next, let's deal with the constant terms:
8 + 9

Adding 8 and 9 gives us 17.

Now we can combine the simplified terms:
-12x + 17

The simplified expression is -12x + 17.
