x + 30% x = - 1,3
x ( 100% + 30% ) = - 1,3
x . 130% = - 1,3
x = - 1,3 : 130%
x = - 1,69
x + 30% x = - 1,3
x ( 100% + 30% ) = - 1,3
x . 130% = - 1,3
x = - 1,3 : 130%
x = - 1,69

tìm x
tìm x biết:
a,\(7,5x:\left(9-6\frac{13}{21}\right)=2\frac{13}{25}\)
b,\(\frac{\left(1,16-x\right)\cdot5,25}{\left(10\frac{5}{9}-7\frac{1}{4}\right)\cdot2\frac{2}{17}}\)=75%
Tìm x :
\(\frac{(1,16-x).5,25}{(10\frac{5}{9}-7\frac{1}{4}).2\frac{2}{17}}\)= 75 phần trăm .
Tìm x, biết:
\(\frac{3}{\left(x+2\right)\left(x+5\right)}+\frac{5}{\left(x+5\right)\left(x+10\right)}+\frac{7}{\left(x+10\right)\left(x+17\right)}=\frac{x}{\left(x+2\right)\left(x+17\right)}\left(x\notin-2;-5;-10;-17\right)\)
\(\frac{2}{\left(x-1\right)\left(x-3\right)}+\frac{5}{\left(x-3\right)\left(x-8\right)}+\frac{12}{\left(x-8\right)\left(x-20\right)}-\frac{1}{x-20}=-\frac{3}{4}\)
Với \(x\notin1;3;8;20\)
\(\frac{x+1}{10}+\frac{2+1}{11}\frac{x+1}{12}=\frac{x+1}{13}+\frac{x+1}{14}\)
