Identify and Group Like Terms: Identify and group like terms.We have the terms 2y and −4y which are like terms because they both contain the variable y. We also have the terms 2x and x which are like terms because they both contain the variable x. The constants −2, +5, and −6 are like terms as well because they are all real numbers without variables.Grouping like terms, we get: (2y−4y)+(2x+x)+(−2+5−6).
Combine Like Terms with y: Combine the like terms that contain the variable y.2y−4y=−2y.
Combine Like Terms with x: Combine the like terms that contain the variable x.2x+x=3x (since x is the same as 1x).
Combine Constant Terms: Combine the constant terms.−2+5−6=3−6=−3.
Write Simplified Expression: Write the simplified expression with the combined like terms.The simplified expression is −2y+3x−3.
