Question

z/z+15=4/9 give 50 points​

Answer 1

$\frac{z}{z} + 15 = \frac{4}{9}$

$= > 9z + 270 = 8$

$= > 9z = 8 - 270$

$= > 9z = - 262$

$= > z = \frac{ - 262}{9}$

Answer 2

$\bigstar$ Solution :

$\bigstar$ Given :   $\frac{z}{z+15}=\frac{4}{9}$

$\bigstar$ To Find : To Evaluate the given equation

$\bigstar$ Explanation :

$\implies \frac{z}{z+15}=\frac{4}{9}\\\\ =>9z=4(z+15)\\\\=>9z=4z+4(15)\\\\=>9z-4z=60\\\\=>5z=60\\\\=>z=12$
