Question

What is the value of 8(y + 5) / 3(3y + 7) if y = 3

Answer 1

Short Answer B
Remark
I'm going to interpret this as
$\frac{8(y + 5)}{[3*(3y + 7)]}$

Step One
Before removing the brackets, the easiest way to start is to substitute for y.
$\frac{8(3 + 5)}{[3*(3*3 + 7)]}$

Step Two
Combine what's inside the brackets.
$\frac{8(8)}{[3*(9 + 7)]}$
$\frac{8(8)}{[3*(16)]}$

Step 3 
Do the multiplication in both brackets in the top and bottom
$\frac{64}{48}$

Step 4
Reduce by dividing both top and bottom by 16.

$\frac{ \frac{64}{16} }{ \frac{48}{16} }$

The answer should be 4/3
