Question

Chong thinks of a Number adds 10 and then multiplies the number so obtained by 3, and get 42. If the number is n then write an equation for this

Answer 1

The equation for this is:
`3(n+10) = 42`

Explanation:

We have that the number though is n.

Adds 10:

This means that now we have:
`n + 10`

Multiplies by 3:

This means that now we have:
`3(n+10)`

Gets 42:

This means that:
`3(n+10) = 42`
