x+11-5=5x
x+11=5x-5
x+11=5-5x

Answer 1

x= johns age
x+11 =5x-5
The answer is C or the third option

Answer 2

The equation is

`x+11=5x-5`

Explanation:

Given that the johns age is x

Also johns age increased by 11 is 5 less than 5 times his age.

we have to find the equation which is used to find the present age of johns.

when johns age is increased by 11 then johns age will be (x+11) yrs

Now, given johns age increased by 11 is 5 less than 5 times his age

⇒
`x+11=5x-5`

`5x-x=11+5`

`4x=16`

`x=(16)/(4)=4 yrs`

The johns age is 4 yrs
