Math Problem Statement

If the value of B from the following expression: (3x^2 - 3y) / [(15)(x-1) * (21)(y+3)] * (5)(2x - y) / (7)(x + y + 3) * (15)(y + 1) / (5x) is given, find the value of 3B - 1/3.

Solution

The image shows the following mathematical problem:

Problem 17: If the value of 3x23y(15)(x1)×(21)(y+3)×(5)(2xy)(7)(x+y+3)×(15)(y+1)(5)x\frac{3x^2 - 3y}{(15)(x-1) \times (21)(y+3)} \times \frac{(5)(2x-y)}{(7)(x+y+3)} \times \frac{(15)(y+1)}{(5)x} is equal to BB, then find the value of 3B133B - \frac{1}{3}.


Let's break down the expression:

We are given that:

B=3x23y(15)(x1)×(21)(y+3)×(5)(2xy)(7)(x+y+3)×(15)(y+1)(5)xB = \frac{3x^2 - 3y}{(15)(x-1) \times (21)(y+3)} \times \frac{(5)(2x-y)}{(7)(x+y+3)} \times \frac{(15)(y+1)}{(5)x}

We need to simplify this expression first, then compute 3B133B - \frac{1}{3}.
