Question

If x/y = 15/4, then find the value of 4x +5y/4x
- 5y​

Answer 1

Answer:

2

Step-by-step explanation:

Since x is equivalent to 15 and y is 4, you substitute it to the equation.

4 (15) + 5 (4) / 4 (15) - 5 (4)

=2

Answer 2

Answer:

Ans : 2

Step-by-step explanation:

Given :

$\frac xy= \frac{15}{4}\\\\Let \ Z=\frac{4x+5y}{4x-5y}\\\\Dividing \ the \ numerator \ and \ denominator \ by\ y \\\\\\Z= \frac {(4 \times \frac xy +5 ) }{(4 \times \frac xy -5)}\\\\Z= \frac { (4 \times \frac{15}{4} +5 )} {(4 \times \frac{15}{4} -5 )}\\\\=\frac {15+5}{15-5}\\\\=\frac {20}{10}\\\\=2$
