Q. Combine the like terms to create an equivalent expression:−k+3k=
Identify like terms: Identify like terms in the expression −k+3k.Like terms are terms that contain the same variable raised to the same power. Here, both terms contain the variable k raised to the first power.
Combine like terms: Combine the like terms by adding their coefficients.The coefficients of −k and 3k are −1 and 3, respectively. When we combine them, we add the coefficients together while keeping the variable k.Calculation: −1+3=2So, −k+3k=2k
