1/2 . x - 4/3 = 1/4
\(\dfrac{1}{2}\cdot x=\dfrac{1}{4}+\dfrac{4}{3}\\ \dfrac{1}{2}\cdot x=\dfrac{19}{12}\\x=\dfrac{19}{12}:\dfrac{1}{2}\\ x=\dfrac{19}{6}\)
7/3 - 2x = 1/3
\(2x=\dfrac{7}{3}-\dfrac{1}{3}\\ 2x=2\\ x=2:2\\ x=1\)
6 : x + 1/3 = 4/5
\(6:x=\dfrac{4}{5}-\dfrac{1}{3}\\ 6:x=\dfrac{7}{15}\\ x=6:\dfrac{7}{15}\\ x=\dfrac{90}{7}\)
