Question

[Ichinose Kaede]

Tìm a: 57/76 bằng 108 /a cộng 48

Answer 1

[Tiến Vỹ]

ta có

\(\frac{57}{76}=\frac{108}{a}+48\)

\(\frac{57}{76}-48=\frac{108}{a}\)

\(-\frac{189}{4}=\frac{108}{a}\)

\(\Rightarrow a=-\frac{16}{7}\)

Answer 2

[Ly Nguyễn]

\(\frac{3}{4}=\frac{108}{a}+48\)

\(\frac{3}{4}-48=\frac{108}{a}\)

\(\frac{-189}{4}=\frac{108}{a}\)

\(\Rightarrow a=108\times4:\left(-189\right)\)

\(\Rightarrow a=\frac{-16}{7}\)
