You can put this solution on YOUR website! Perform the indicated operation and simplify:
6x + 9/3x - 15 * x - 5/4x + 6
Is the middle of this expression really 15 * x? If so, it is can be rewritten 15x. If that is really a plus or minus, then it is the number 15 and x are two different terms. Check this.
First: group the terms of this expression so that those with an x and those that are just numbers are together.
6x + 9/3x - 15x -5/4x + 6 or 6x + 9/3x + x - 5/4x + 6 - 15
9/3 can be simplified to 3. 6-15 can be simplifed to -9
6x + 3x - 15x -5/4x + 6 or 6x + 3x + x - 5/4x - 9
Then, combine the like terms.
(6 + 3 - 15 - 5/4)x + 6 or (6 + 3 + 1 - 5/4)x + - 9
-29/4 x + 6 or 35/4 x - 9
