Những câu hỏi liên quan
Tìm x,y biết :
a) 1-(5/3/8+x-7/5/24): 16/2/3=0
b) (1/6+2/1/12-10,75).x-7= (2/5+3/8-2,225): 0,1
người ta ko bt thì hỏi , đừng có mak ns mấy câu vô văn hóa thế nhá

Tìm x, biết:
2) \(\left(\dfrac{1}{6}+2\dfrac{1}{2}-10,75\right).x-7=\left(\dfrac{2}{5}+\dfrac{3}{8}+0,025\right):0,1\)
2) \(\left(\dfrac{1}{6}+2\dfrac{1}{2}-10,75\right)\cdot x-7=\left(\dfrac{2}{5}+\dfrac{3}{8}+0,025\right):0,1\)
\(\left(\dfrac{1}{6}+\dfrac{5}{2}-\dfrac{43}{4}\right)x-7=\left(\dfrac{2}{5}+\dfrac{3}{8}+\dfrac{1}{40}\right):\dfrac{1}{10}\)
\(-\dfrac{97}{12}x-7=\dfrac{4}{5}\cdot10\)
\(-\dfrac{97}{12}x=8+7\\ -\dfrac{97}{12}x=15\\ x=15:\left(-\dfrac{97}{12}\right)\\ x=-\dfrac{180}{97}\)

Tìm x ,biết :
\(\left(\frac{1}{6}+2\frac{1}{12}-10,75\right).x-7=\left(\frac{2}{5}+\frac{3}{8}x+0.225\right):0,1\)
Đang cần gấp
Nhớ giải ra
(\(\frac{1}{6}\)+2\(\frac{1}{1^2}\)-10,75). x - 7 =(\(\frac{2}{5}\)+ \(\frac{3}{8}\)+ 0,225); 0,1
mình cần gấp nhé
Tìm x biết \(\left(1+2\frac{1}{12}-10,75\right)x-7=\left(\frac{2}{5}+\frac{8}{5}+0,225\right):0,1\)
\(\left(1+2\frac{1}{12}-10,75\right)x-7=\left(\frac{2}{5}+\frac{8}{5}+0,225\right):0,1\)
\(=\left(\frac{37}{12}-\frac{129}{12}\right)x-7=\left(2+\frac{9}{40}\right).10\)
\(=-\frac{23}{3}x=\frac{28}{4}+\frac{89}{4}=\frac{201}{4}\)
\(x=\frac{201}{4}:\left(-\frac{23}{3}\right)=\frac{201}{4}.\left(-\frac{3}{23}\right)=-\frac{603}{92}\)
