Question

7 ( v - 4 ) - 2v = -3

Answer 1

Express the following

7 ( v - 4 ) - 2v = -3 ​

`7(v-4)-2v=-3​`

Step 1: Collect like terms

`\begin{gathered} 7(v-4)-2v=-3 \\ 7v-28-2v=-3 \\ 7v-2v-28=-3 \\ 5v-28=-3 \end{gathered}`

Step 2: Evaluate the expression

`\begin{gathered} 5v-28=-3 \\ 5v=-3+28 \\ 5v=25 \\ \text{divide both side by 5} \\ 5v=25 \\ (5v)/(5)=(25)/(5) \\ v=5 \end{gathered}`

Therefore the correct value of v = 5
