Final answer:
To perform the indicated operation, you need to combine like terms by adding the coefficients of the variables. The simplified expression is 2x + 1/10y.
Step-by-step explanation:
To perform the indicated operation, we need to combine like terms. We can do this by adding the coefficients of the terms with the same variables.
Starting with the x terms, we have: x + 3x - 2x = 2x.
Next, looking at the y terms, we have: 2/10y - 1/10y + 5/10y = (2 - 1 + 5)/10y = 1/10y.
Putting it all together, the simplified expression is: 2x + 1/10y.
