Given the numerical expression:

-6(k-3)=-27+3k

Solution:

In order to solve the numerical expression, we distribute first -6 on each value on the parenthesis. It must be taken to note that when a negative number is multiplied or introduced to a negative number, the sign becomes positive. It is a general rule that opposite signs will result to a negative number, while the same signs will result to a positive number.

-6(k-3)=-27+3k

-6k + 3 = 27 + 3k

Transpose -6k + 3k on the other side of the equation. Note that in transposing a number, the sign changes.

= 27 + 3k + 6k -3

=9k -24

To find for the value of k, we transpose -24 on the other side and divide both sides by 9.

24 = 9k

k = 24/9 or 7/3

Final answer:

Simplified form:9k -24

k = 7/3
