\(x+\dfrac{11}{5}=\)\(\dfrac{3}{5}\)
\(x\) \(=\)\(\dfrac{3}{5}-\dfrac{11}{5}\)
\(x\) \(=\)-\(\dfrac{8}{5}\)
x + 11/5 = 2/5 : 2/3
x + 11/5 = 3/5
x = 3/5 - 11/5
x = -8/5
\(x-\frac{1}{4}=\frac{5}{3}\)
\(\Rightarrow x=\frac{23}{12}\)
\(x:\frac{5}{11}=22\)
\(\Rightarrow x=10\)
\(\frac{2}{4}+x=1\)
\(\Rightarrow x=\frac{1}{2}\)
\(x-\frac{11}{5}=\frac{2}{5}:\frac{2}{3}\)
\(\Rightarrow x-\frac{11}{5}=\frac{3}{5}\)
\(\Rightarrow x=\frac{18}{5}\)
\(a)x-\frac{1}{4}=\frac{5}{3}\)
\(\Rightarrow x=\frac{5}{3}+\frac{1}{4}=\frac{23}{12}\)
\(b)x:\frac{5}{11}=22\)
\(\Rightarrow x=22.\frac{5}{11}=10\)
\(c)\frac{2}{4}+x=1\)
\(x=1-\frac{2}{4}=\frac{1}{2}\)
\(d)x-\frac{11}{5}=\frac{2}{5}:\frac{2}{3}\)
\(\Rightarrow x-\frac{11}{5}=\frac{3}{5}\)
\(\Rightarrow x=\frac{3}{5}+\frac{11}{5}=\frac{14}{5}\)
a) \(x+\dfrac{4}{9}=\dfrac{5}{27}\)
\(x=\dfrac{5}{27}-\dfrac{4}{9}\)
\(x=-\dfrac{7}{27}\)
b) \(x-\dfrac{4}{11}=\dfrac{7}{33}\)
\(x=\dfrac{7}{33}+\dfrac{4}{11}\)
\(x=\dfrac{19}{33}\)
c) \(\dfrac{8}{5}-x=\dfrac{1}{3}\times\dfrac{2}{5}\)
\(\dfrac{8}{5}-x=\dfrac{2}{15}\)
\(x=\dfrac{8}{5}-\dfrac{2}{15}\)
\(x=\dfrac{22}{15}\)
d) \(x-\dfrac{3}{4}=\dfrac{1}{2}+\dfrac{2}{6}\)
\(x-\dfrac{3}{4}=\dfrac{5}{6}\)
\(x=\dfrac{5}{6}+\dfrac{3}{4}\)
\(z=\dfrac{19}{12}\)
\(1.x-\dfrac{2}{3}\times\left(x+9\right)=1\)
\(x-\dfrac{2}{3}\times x-6=1\)
\(x\times\left(1-\dfrac{2}{3}\right)=7\)
\(x\times\dfrac{1}{3}=7\)
\(x=21\)
\(2.x-\dfrac{11}{15}=\dfrac{3+x}{5}\)
\(\dfrac{15x}{15}-\dfrac{11}{15}=\dfrac{9+3x}{15}\)
\(15x-11=9+3x\)
\(12x=20\)
\(x=\dfrac{5}{3}\)
