Question

Fourteen more than 4 times a number is 42what is equation?what is solution?

Answer 1

We have to express this phrase in mathematical terms.

We call the number x.

Then, four times a number is "4x".

Fourtenn more than 4x is "4x+14", and this is equal to 42.

Then, we can write:

`4x+14=42`

And solve as:

`\begin{gathered} 4x+14=42 \\ 4x=42-14 \\ 4x=28 \\ x=(28)/(4) \\ x=7 \end{gathered}`

Answer: the equation is 4x+14=42 and the solution is x=7
