Hi Mateo,

The product of two factors: 8 and three less than x. The second factor can be written: x minus 3 = x-3.

Thus the equivalent algebraic expression is the product: 8 * (x - 3) or simply 8x - 24 using the distributive property.

Note the parentheses which in this case tell us to use the distributive property. A very common error in algebra is to forget the parentheses..
