Answer 2

Therefore x =29.

Step-by-step explanation:

Given that,

$\frac{a}{3} =\frac{b}{4} =\frac{3a+5b}{x} =r(say)$

Then

$\frac{a}{3} =r$

⇒a = 3r

and,

$\frac{b}{4} =r$

⇒b=4r

Therefore,

$\frac{3a+5b}{x} =r$

$\Rightarrow \frac{3.3r+5.4r}{x} =r$

$\Rightarrow \frac{9r+20r}{x} =r$

$\Rightarrow \frac{29r}{x} =r$

$\Rightarrow x=29$

Therefore x =29.
