1/3 x + 2/5 x - 2/5 = 0
1/3 x + 2/5 x = 0 + 2/5
11/15 x = 2/5
x = 2/5 : 11/15 = 6/11
1/3 x + 2/5 x - 2/5 = 0
1/3 x + 2/5 x = 0 + 2/5
11/15 x = 2/5
x = 2/5 : 11/15 = 6/11
làm ơn giúp mk nha, tìm x
\(3\left(x-\frac{1}{2}\right)-5\left(x+\frac{3}{5}\right)=-x+\frac{1}{5}\)
Tìm x:
a)\(\left(3x-1\right)\left(-\frac{1}{2}x+5\right)=0\)
b)\(-5\left(x+\frac{1}{5}\right)-\frac{1}{2}\left(x-\frac{2}{3}\right)=\frac{3}{2}x-\frac{5}{6}\)
1,Tìm x: a,\(\frac{x+2}{5}=\frac{1}{x-2}\) b,\(\left(x-\frac{2}{9}\right)^3=\left(\frac{2}{3}\right)^6\) c,\(\left(8x-1\right)^{2\cdot n+1}=5^{2\cdot n+1}\)
2,Tìm x,y bít: a,\(x^2+\left(y-\frac{1}{10}\right)\cdot4=0\) b,\(\left(\frac{1}{2}\cdot x-5\right)^{20}+\left(y^2-\frac{1}{4}\right)^{10}< hay=0\)
Làm giúp cấy nha, tui ko làm đc toán, dốt toán lắm. Sáng mai là đi học thêm zồi. Thanks bạn trước nhen :)
Tìm x, biết :
a) \(\left(\frac{3}{4}.x-\frac{9}{16}\right).\left(\frac{1}{3}+\frac{-3}{5}:x\right)=0\)
b) \(\left(x-\frac{1}{3}\right).\left(x+\frac{2}{5}\right)>0\)
c) \(\left(x+\frac{3}{5}\right).\left(x+1\right)< 0\)
Tìm x, biết :
a) \(\left(\frac{3}{4}.x-\frac{9}{16}\right).\left(\frac{1}{3}+\frac{-3}{5}:x\right)=0\)
b) \(\left(x-\frac{1}{3}\right).\left(x+\frac{2}{5}\right)>0\)
c) \(\left(x+\frac{3}{5}\right).\left(x+1\right)< 0\)
Tìm x biết :
a, \(\frac{1}{3}.x+\frac{2}{5}.\left(x-1\right)=0\)
b,\(3.\left(x-\frac{1}{2}\right)-5.\left(x+\frac{3}{5}\right)=x+\frac{1}{5}\)
tìm x biết :
a. \(\frac{1}{3}.x+\frac{2}{5}.\left(x-1\right)=0\)
b.\(3.\left(2.x-\frac{5}{4}\right)=\left(3-1\frac{1}{2}\right).\left(x-\frac{1}{2}\right)\)
a ) tìm : \(\frac{1}{15}+\frac{1}{35}+\frac{1}{63}+\frac{1}{99}+\frac{1}{143}+\frac{1}{195}\)
b ) tìm x : 1 - ( \(1-\left(5\frac{3}{8}+x-7\frac{5}{24}\right):\left(-16\frac{2}{3}\right)=0\)
giúp mình nha!
Tìm x
\(\left(2x+\frac{3}{5}\right)^2-\frac{9}{25}=0\)
\(3\left(3x-\frac{1}{2}\right)^3+\frac{1}{9}=0\)
\(-5\left(x+\frac{1}{5}\right)-\frac{1}{2}\left(x-\frac{2}{3}\right)=\frac{3}{2}x-\frac{5}{6}\)
\(3\left(x-\frac{1}{2}\right)-5\left(x+\frac{3}{5}\right)=-x+\frac{1}{5}\)
giải nhanh hộ mình với, mai mình nộp rồi
