Question

What is p/20=(p-4)/5?

Answer 1

p =
`(16)/(3)`

Explanation:

Given

`(p)/(20)` =
`(p-4)/(5)` ( cross- multiply )

20(p - 4) = 5p ← distribute left side

20p - 80 = 5p ( subtract 5p from both sides )

15p - 80 = 0 ( add 80 to both sides )

15p = 80 ( divide both sides by 15 )

p =
`(80)/(15)` =
`(16)/(3)`
