Question

5/2+5x=2x-1/3

Ngọc Lan Tiên Tử · Accepted Answer

$\frac{5}{2}+5x=2x-\frac{1}{3}$

=> $5x-2x=-\frac{5}{2}+\frac{1}{3}$

=> $3x=-\frac{17}{6}$

=> $x=-\frac{17}{6}:3=-\frac{17}{18}$

Vậy $x\in\left\{-\frac{17}{18}\right\}$Câu trả lời: $\frac{5}{2}+5x=2x-\frac{1}{3}$

=> $5x-2x=-\frac{5}{2}+\frac{1}{3}$

=> $3x=-\frac{17}{6}$

=> $x=-\frac{17}{6}:3=-\frac{17}{18}$

Vậy $x\in\left\{-\frac{17}{18}\right\}$

$\frac{5}{2}$ + 5x=2x−1352+5x=2x−13

=> 5x−2x=−52+135x−2x=−52+13

=> 3x=−1763x=−176

=> x=−176:3=−1718x=−176:3=−1718
