Question

Simplify the expression 5(-7 + 3k)

Answer 1

The given expression is,

`5(-7+3k)`

Opening the brackets and multiplying each term inside the bracket with 5, we get,

`\begin{gathered} \lbrack5*(-7)\rbrack+(5*3k)=-35+15\text{ k} \\ 15k=35 \\ k=(35)/(15)=2.33 \end{gathered}`

The simplified expression is 15k = 35 and the value of k is 2.33.
