Question

-2 (3y + 2) - 7z - 4(3z+ 8y )
how do you simplify expression with distribution?​

Answer 1

-38y - 19z - 4

Explanation:

You meses to multiply the numbers outside the brackets with the values inside.

First you have -2(3y+2) so you multiply -2 with 3y = -6y and then you multiply the -2 with the +2 = -4. So you're left with -6y - 4 - 7z - 4(3z+8y).

Now do the same with the last one, multiply -4 by 3z = -12z, then multiply -4 with +8y = -32y. You're left with -6y-4-7z-12z-32y.

Now we change the order to make it easier and we have -32y-6y-12z-7z-4, we make the subtractions and we get -38y - 19z - 4
