[tex]2x - 1 = - 5 \\ 2x = - 5 + 1 \\ 2x = - 4 \\ x = - \frac{4}{2} \\ x = - 2[/tex]
[tex]0.5x - 1.3 = 2.7 \\ \frac{5}{10} x - \frac{13}{10 } = \frac{27}{10} \\ 5x - 13 = 27 \\ 5x = 27 + 13 \\ 5x = 40 \\ x = 8[/tex]
[tex] \sqrt{3x } = 2 \sqrt{6} \\ x = 2 \sqrt{6} \div \sqrt{3} \\ x = 2 \sqrt{2} [/tex]
Sper sa fie bine!
