Odpowiedź:
x+2/9+x-1/3=1
2x=1+1/3-2/9
2x=1 1/9
x=5/9
Szczegółowe wyjaśnienie:
[tex]x + \frac{2}{9} + x - \frac{1}{3} = 1 \\ x + x = 1 - \frac{2}{9} + \frac{1}{3} \\ x + x = \frac{9}{9} + \frac{2}{9} - \frac{3}{9} \\ 2x = \frac{10}{9} || \div 2 \\ x = \frac{10}{9} \div \frac{2}{1} \\ x = \frac{10}{9} \times \frac{1}{2} = \frac{10}{18} = \frac{5}{9} [/tex]
x = 5/9
