Q. Combine the like terms to create an equivalent expression:−k+3k=□
Identify like terms: Identify like terms in the expression.In the expression −k+3k, both terms are like terms because they contain the variable k.
Combine like terms: Combine the like terms by adding their coefficients.The coefficient of −k is −1 and the coefficient of 3k is 3. When we combine them, we get (−1+3)k.
Perform addition of coefficients: Perform the addition of the coefficients. −1+3 equals 2, so the expression becomes 2k.
Write simplified expression: Write down the simplified expression.The equivalent expression after combining like terms is 2k.
