Question

Evaluate the expression when b=-7 and c=7.-3b + c

Answer 1

Given that

`b=-7,c=7`

Evaluate the expression below

`-3b+c`

By substituting the values of b =-7 and c = 7 in the expression, we will have

`\begin{gathered} -3b+c \\ -3(-7)+7 \\ =21+7 \\ =28 \end{gathered}`

Hence,

The final answer = 28
