Question

7x-15y=4x+y use properties of proportion to find the value of 9x+5y/9x-5y

Answer 1

$Given \: 7x - 15 y = 4x + y$

$\implies 7x - 4x = y + 15y$

$\implies 3x = 16y$

/* Multiplying both sides by 3 , we get */

$\implies 9x = 48y \: ---(1)$

$Now, Value \:of \:\frac{9x+5y}{9x-5y} \\= \frac{48y+5y}{48y-5y} \: [From \:(1) ]$

$= \frac{53y}{43y}\\= \frac{53}{43}$

Therefore.,

$\red {Value \:of \:\frac{9x+5y}{9x-5y}}\green { = \frac{53}{43}}$

Answer 2

Answer:

$\frac{53}{43}$

Step-by-step explanation:

7x-15y=4x+y

7x-4x=y+15

3x=16y

Multiply by 3 on both side

3×3x=3×16y

9x=48y

The value of

$\frac{9x + 5y}{9x - 5y}$

using 9x=48y

$\frac{48y + 5y}{48y - 5y} \\ = \frac{53y}{43y} \\ = \frac{53}{43}$

hope IT HELPs.....
