Question

(7,25x+11/9)÷(-2/3)^2=-3/5

Answer 1

\(\left(7,25x+\frac{11}{9}\right)\div\left(\frac{-2}{3}\right)^2=\frac{-3}{5}\)

\(\left(\frac{29}{4}x+\frac{11}{9}\right)\div\frac{4}{9}=\frac{-3}{5}\)

\(\frac{29}{4}x+\frac{11}{9}=\frac{-3}{5}.\frac{4}{9}\)

\(\frac{29}{4}x+\frac{11}{9}=\frac{-4}{15}\)

\(\frac{29}{4}x=\frac{-4}{15}-\frac{11}{9}\)

\(\frac{29}{4}x=\frac{-67}{45}\)

\(x=\frac{-67}{45}\div\frac{29}{4}\)

\(x=\frac{-268}{1305}\)

Answer 2

(7,25x+11/9)÷(-2/3)^2=-3/5 (29/4.x+11/9)÷4/9=-3/5 29/4.x+11/9=-3/5.4/9 29/4.x+11/9=-4/15 29/4.x=-4/15-11/9 29/4.x=-67/45 x=-67/45÷29/4 x=-268/1305 Vậy x=-268/1305 Chúc bạn hok tốt♡♡♡
