Question

if 3a+4b/3a-4b=11/-5 then a/b= ?​

Answer 1

$\sf \red{ \frac{3a + 4b}{3a - 4b} = \frac{11}{ - 5} }$

$\sf cross \: multiply \: the \: each \: of \: the \: following$

$\sf - 5(3a + 4b) = 11(3a - 4b)$

$\sf - 15a - 20b = 33a - 44b$

$\sf 44b - 20b = 33a + 15a$

$\sf 24b \: = 48a$

$\sf \frac{24}{48} = \frac{a}{b}$

$\boxed{ \boxed{ \sf \frac{1}{2} = \frac{a}{b}}}$
