Explicație pas cu pas:
[tex]3x + \frac{1}{3} + \frac{2}{4} + \frac{3}{5} = 5[/tex]
[tex]3x + \frac{20 + 30 + 36}{60} = 5[/tex]
[tex]3x + \frac{86}{60} = 5[/tex]
[tex]3x = 5 - \frac{43}{30} [/tex]
[tex]3x = \frac{150 - 43}{30} [/tex]
[tex]3x = \frac{107}{30} [/tex]
[tex]x = \frac{107}{30} \div 3[/tex]
[tex]x = \frac{107}{30} \times \frac{1}{3} [/tex]
[tex]x = \frac{107}{90} [/tex]
