Question

Hello I need some help on my math homework solving equation or formula for variable

Answer 1

SOLUTION;

We are to make x the subject of the formula in the given equation;

`(3ax-n)/(5)\text{ = -4}`
`\begin{gathered} 3ax\text{ - n = -4(5)} \\ 3ax\text{ - n = -20} \\ 3ax\text{ = -20+n} \\ or \\ 3ax\text{ = n - 20} \\ \text{dividing both sides by 3a} \\ \\ (3ax)/(3a)=\text{ }(n-20)/(3a) \\ \\ x\text{ = }(n-20)/(3a) \end{gathered}`
