Identify Like Terms: Identify like terms in the expression −9w+6w+3w+−3w. Like terms are terms that contain the same variable raised to the same power. In this case, all terms are like terms because they all contain the variable w raised to the first power.
Combine Like Terms: Combine the like terms by adding or subtracting the coefficients.−9w+6w+3w+−3w= (−9w+6w)+(3w+−3w)= −3w+0w= −3w
Final Simplified Expression: Since there are no more like terms to combine, the expression is now simplified. The final simplified expression is −3w.
