Question

if 5a + 3b / 2a - 3b = 23 / 5, then the value of a : b is?​

Answer 1

Answer:

The answer is 4:1

Step-by-step explanation:

Given  $\frac{5a+3b}{2a-3b}=\frac{23}{5}$

Cross multiply

      $\Rightarrow 25a+15b=46a-69b\\\Rightarrow 15b+69b=46a-25a\\\Rightarrow 84b=21a\\\Rightarrow \frac{84}{21}=\frac{a}{b}\Rightarrow 4=\frac{a}{b}\\\therefore a:b=4:1$
