Yes I can, MissSmartiez at your service ;)!
This calls for the distributive property. Distributive property, essentially, takes the outside value (in this case 4) and multiply it to the inside value(s) (in this case 2x and [+]3) Thus, it's basically 4 * 2x + 4 *3.
4 multiplied by 2x is 8x.
4 times 3 is equivalent to 12.
Therefore the solution is 8x + 12.
