Question

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

Answer 1

Solution

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

$\begin{gathered} 5v-28=-3 \\ 5v=-3+28 \\ 5v=25 \\ \text{divide both side by 5} \\ 5v=25 \\ \frac{5v}{5}=\frac{25}{5} \\ v=5 \end{gathered}$

Therefore the correct value of v = 5
