Question

 Tìm y biết : 7/4 - y x 5/6 = 1/2 + 1/3 

trả lời tìm y:

Answer 1

7/4-y x 5/6 = 1/2+1/3

7/4-y x 5/6=5/6

      y x 5/6=7/4-5/6

      y x 5/6=11/12

               y=11/12 : 5/6

               y=11/10

Answer 2

\(\frac{7}{4}-y\times\frac{5}{6}=\frac{1}{2}+\frac{1}{3}\)

\(\frac{7}{4}-y\times\frac{5}{6}=\frac{5}{6}\)

\(\frac{7}{4}-y=\frac{5}{6}\div\frac{5}{6}\)

\(\frac{7}{4}-y=1\)

\(y=1+\frac{7}{4}\)

\(y=\frac{11}{4}\)

Answer 3

hãy trả lời rồi kb cho mình nhé

Answer 4

7/4-y x 5/6 = 1/2+1/3

7/4-y x 5/6=5/6

      y x 5/6=7/4-5/6

      y x 5/6=11/12

               y=11/12 : 5/6

               y=11/10

Đảm bảo đúng!!!!

   

Answer 5

7/4 - y x 5/6 = 3/6 + 2/6

7/4 - y x 5/6 = 5/6

y x 5/6          =7/4 -5/6

y x 5/6          = 21/12 - 10 /12

y x 5/6           = 11/12

y                    = 11/12 : 5/6

y                    =11/12 x 6/5

y                    =11/10
