Question

4/7+y=5/8-1/4 Tìm y

Answer 1

\(\frac{4}{7}+y=\frac{5}{8}-\frac{1}{4}\)

\(\frac{4}{7}+y=\frac{3}{8}\)

           \(y=\frac{3}{8}-\frac{4}{7}\)

           \(y=-\frac{11}{56}\)

hình như bạn ra sai đề rồi

Answer 2

\(\frac{4}{7}+y=\frac{3}{8}\)

\(y=\frac{3}{8}-\frac{4}{7}=-\frac{11}{56}\)

Answer 3

\(\frac{4}{7}+y=\frac{5}{8}-\frac{1}{4}\)

\(\frac{4}{7}+y=\frac{5}{8}-\frac{2}{8}\)

\(\frac{4}{7}+y=\frac{3}{8}\)

          \(y=\frac{3}{8}-\frac{4}{7}\)

        \(y=\frac{21}{56}-\frac{32}{56}\)

       \(y=-\frac{11}{56}\)

Answer 4

\(\frac{4}{7}+y=\frac{5}{8}-\frac{1}{4}\)

\(\frac{4}{7}+y=\frac{3}{8}\)

\(\frac{3}{8}-\frac{4}{7}=\)\(\frac{11}{56}\)

Answer 5

\(\frac{4}{7}+y=\frac{5}{8}-\frac{1}{4}\)

\(\frac{4}{7}+y=\frac{3}{8}\)

           \(y=\frac{3}{8}-\frac{4}{7}\)

           \(y=-\frac{11}{56}\)
