Question

If you subtract 8 from 7 times a certain number, you end up with 34. what is the number?​

Answer 1

If we call the unknown number x, we have:

• 7 times a certain number is
  `7x`
• If we subtract 8, we have
  `7x-8`

If this equals 34, we have

`7x-8=34`

Add 8 to both sides:

`7x=42`

Divide both sides by 7:

`x=6`
