Answer 1

Hazel Anglin

Simplifying this give us #3k+11#. See below on the steps.

So before we start simplifying this, we need to distribute the negative sign to #(2k-1)# which gives us this:

#5k+10-2k+1#

Combining like terms to simplify this gives us:

#3k+11#

To simplify (5k + 10) - (2k - 1), you distribute the negative sign inside the parentheses and then combine like terms:

(5k + 10) - (2k - 1) = 5k + 10 - 2k + 1 = (5k - 2k) + (10 + 1) = 3k + 11
