Answer 1

Hi Dania

 

OK, so product of 8 and seven less than a number

 

What does product mean  (hopefully you know that it means to multiply)

 

What is seven less than a number, it tells us to use x as the number.  Therefore, seven less than the number will be

 

x - 7  (less than means subtraction

 

now take the product of 8 and (x-7)

 

8(x-7)

 

and if we mutilpy out we get 8x - 56

 

Hope this helps
