A pole is x metres long, is broken into two parts. one part is 5 metres long.
To find : what is the length of the other part ?
if the other part is 6 metres long write an equation to find the value of x.
solution : length of pole = x metres
⇒length of 1st part + length of 2nd part = x
⇒5 + length of 2nd part = x
⇒length of 2nd part = (x - 5) metres .....(1)
again the other part is 6 metres long.
it means length of 2nd part = (x - 5) = 6 [ from equation (1) . ]
⇒x = 5 + 6
⇒x = 11 metres
Therefore the value of x is 11 metres.
