Question

What is the solution to the equation ? 5{n-1 over 10}= 1 over 2

Answer 1

n = 2

Explanation:

Given

5(
`(n-1)/(10)` ) =
`(1)/(2)` ← distribute parenthesis on left side

`(n-1)/(2)` =
`(1)/(2)`

Since denominators are both 2 then equate numerators

n - 1 = 1 ( add 1 to both sides )

n = 2
