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:

$x=6$
