\(\frac{2016+x}{x}+\frac{2520+x}{x}+\frac{3024+x}{x}=\frac{2016}{x}+\frac{x}{x}+\frac{2520}{x}+\frac{x}{x}+\frac{3024}{x}+\frac{x}{x}\)
\(=\frac{2016+2520+3024}{x}+3\)
\(=\frac{7560}{x}+3\)
\(\frac{7560}{x}+3=2523\)
\(\frac{7560}{x}=2520\)
\(x=\frac{7560}{2520}\)
\(x=3\)
Tìm x \(\frac{2016+x}{x}+\frac{2520+x}{x}+\frac{3024+x}{x}=2523\)
Tìm x biết \(\frac{2016+x}{x}+\frac{2520+x}{x}+\frac{3024+x}{x}=2523\)
tìm x , biết :
\(\frac{x-2019}{2018}+\frac{x-2018}{2017}=\frac{x-2017}{2016}+\frac{x-2016}{2015}\)
Tìm x thỏa mãn \(\frac{x}{2016}+\frac{x+1}{2017}=\frac{x+2}{2018}\)\(+\frac{x+3}{2019}\)
Dễ thấy bài này kết quả bằng 2016 rồi nhưng mình cần cách giải
Ai nhanh và đúng sẽ nhận tích nhe !
Tìm số tự nhiên x thỏa mãn:
