Question

Решите уравнения плиз:
а)
17/20 - х= 14/20 - 3/20 
б)
8/15 - 7/15 + у= 14/15 

Answer 1

а) $dfrac{17}{20}-x=dfrac{14}{20}-dfrac3{20}\dfrac{17}{20}-x=dfrac{11}{20}\x=dfrac{17}{20}-dfrac{11}{20}\x=dfrac{6}{20}=dfrac3{10}$

б) $dfrac8{15}-dfrac7{15}+y=dfrac{14}{15}\dfrac1{15}+y=dfrac{14}{15}\y=dfrac{14}{15}-dfrac1{15}\y=dfrac{13}{15}$
