Question

49Which equation could you use to solve for x in the proportion 5 - x?O 4x - 14O 4x-45O 5x-13O 5x - 36

Answer 1

`\begin{gathered} (4)/(5)=(9)/(x) \\ \text{Solve for x:} \\ \text{Multiply both sides by x:} \\ (4x)/(5)=9 \\ \text{Multiply both sides by 5:} \\ 4x=45 \\ \text{Divide both sides by 4:} \\ (4x)/(4)=(45)/(4) \\ x=(45)/(4) \\ \end{gathered}`
