Q. Combine the like terms to create an equivalent expression:−2k−(−5)+1
Identify like terms and constants: Identify like terms and constants in the expression −2k−(−5)+1.The like terms are the terms with the variable k, and the constants are the numbers without variables. In this expression, −2k is the only like term, and −(−5) and +1 are constants.
Simplify the constants: Simplify the constants in the expression −2k−(−5)+1.To simplify the constants, we need to subtract −5 from −2k and then add 1. Subtracting a negative is the same as adding a positive, so −(−5) becomes +5.Expression after simplifying constants: −2k+5+1
Combine the constants: Combine the constants 5 and 1.Now we add the constants together.5+1=6Expression after combining constants: −2k+6
