Question

14V + 25 − 5V = 4(V + 25)

Answer 1

Step 1

Given; 14V + 25 − 5V = 4(V + 25)

Required; Find V

Step 2

`\begin{gathered} 14V+25-5V=4(V+25) \\ \mathrm{Group\:like\:terms} \\ 14V-5V+25=4\left(V+25\right) \end{gathered}`
`\begin{gathered} Add\:similar\:elements \\ 9V+25=4\left(V+25\right) \\ Expand\text{ the bracket} \\ 9V+25=4V=100 \end{gathered}`
`\begin{gathered} 9V-4V=100-25 \\ 5V=75 \\ (5V)/(5)=(75)/(5) \\ V=15 \end{gathered}`

Answer;

`V=15`
