Write a word problem that would have the equation 8x - 4 = 28
xxMikexx [17]

Answer:

John's mother has the present age that is four less than the 8 times the present age of John.

If his mother has the age of 28 years now, then find John's present age.

Step-by-step explanation:

We have to write a word problem that would have the equation 8x - 4 = 28.

John's mother has the present age that is four less than the 8 times the present age of John.

If his mother has the age of 28 years now, then find John's present age.

So, if we consider the age of John as x years, then we will get the equation as 8x - 4 = 28. (Answer)
