Question

Finish Consider the equation, where p is a real number coefficient. -; (px - 2) = 9 What is the value of x in the equation? 3 OI= O O r = OI= OI= < > Fin

Answer 1

`\begin{gathered} (1)/(2)(px-2)=9 \\ (px-2)/(2)=9 \\ \text{Cross multiply and you have;} \\ px-2=18 \\ \text{Add 2 to both sides of the equation} \\ px-2+2=18+2 \\ px=20 \\ \text{Divide both sides by p} \\ (px)/(p)=(20)/(p) \\ x=(20)/(p) \end{gathered}`

The answer is;

x = 20/p
