-14k - 14
Step-by-step explanation:
1) Begin by distributing the 5, located outside of the parentheses.
2) Distributing is done by taking the number outside the parentheses and multiplying it with the numbers inside.
3) 5 * - 3.4 5 * - 7
4) After distributing, set up the numbers together so you are able to combine the like terms.
5) - 17k - 35 + 3k + 21
6) In this particular expression, the like terms are the integers and whole numbers, as well as the coefficients which contain the same variable.
7) - 35 + 21 + - 17k + 3k
8) In this step, combine the like terms from the expression above in step 7, use step 6 as a reference. - 14 - 14k
9) Coefficents are always prioritized from a greatest to least order, therefore the simplified expression would be - 14k - 14.
