Question

5/13 = X+4/52

X-3/17=24/51

Спасибо)

Answer 1

$frac{5}{13}=X+frac{4}{52}$

 

$X=frac{5}{13}-frac{4}{52}=frac{20-4}{52}=frac{16}{52}=frac{4}{13}$

 

 

$X-frac{3}{17}=frac{24}{51}$

 

$X=frac{24}{51}+frac{3}{17}=frac{24+9}{51}=frac{33}{51}$

 

Answer 2

$frac{5}{13}=x+frac{4}{52}$

$frac{5}{13}=x+frac{1}{13}$

$frac{5}{13}=frac{13x+1}{13}$

$13x+1=frac{13*5}{13}$

$13x+1=5$

$13x=5-1$

$13x=4$

$x=frac{4}{13}$

 

------------------

 

$x-frac{3}{17}=frac{24}{51}$

$frac{17x-3}{17}=frac{8}{17}$

$17x-3=8$

$17x=8+3$

$17x=11$

$x=frac{11}{17}$
