Tìm x,biết:
1) 3\(\dfrac{1}{4}\).x+(\(\dfrac{-7}{6}\)).x-1\(\dfrac{2}{3}\)=\(\dfrac{5}{12}\)
2) \(\dfrac{2}{3}\).x-\(\dfrac{1}{2}\).x =\(\dfrac{5}{12}\)
3) (x+\(\dfrac{1}{5}\))2 +\(\dfrac{17}{25}\)=\(\dfrac{26}{25}\)
4) -1\(\dfrac{5}{27}\)-(3x-\(\dfrac{7}{9}\))3=\(\dfrac{-24}{27}\)
Giúp mình nhé mình đang cần gấp
