2x - 16 divided by 4

Answer 1

So, just like 1/5 + 3/5 = 4/5, we can do the opposite.

7/8 = 2/8 + 5/8 = 1/4 + 5/8, for example.

(2x - 16)/4 = 2x/4 - 16/4 = x/2 - 4

Answer 2

When you divide an expression by a number, you have to divide every term in the expression by the number you are dividing by:

For example, if we divide a+b by c, we get:

(a/c)+(b/c)

Applying this to your question, we want to divide the expression 2x-16 by 4:

(2x/4)-(16/4)

Simplified we have:

(x/2)-4
