a,6² . x - 5² . x = 11. 2².
b,3 (x+2) - x = 5.
c,2022 - (x+ 2022) = 15 + (x-75)

(2x - \(\dfrac{7}{3}\)) : 2\(\dfrac{3}{11}\) + 0,6=16%

(2x - \(\dfrac{7}{3}\)) : 2\(\dfrac{3}{11}\) + 0,6 = 16%

\(-\dfrac{1}{5}\) . ( x - 0,25) = 1\(\dfrac{1}{2}\) - ( \(\dfrac{-1}{2}\))^2

\(-\dfrac{1}{5}\) . (x-0,25) = 1\(\dfrac{1}{2}\) - (\(\dfrac{-1}{2}\))^2

 \(\dfrac{5}{8}\) - x = \(-\dfrac{3}{20}\) + \(\dfrac{1}{6}\)

\(\dfrac{5}{8}\) - x = \(-\dfrac{3}{20}\) + \(\dfrac{1}{6}\)
