[tex] \frac{x - 1}{3} + 2 = 1 \frac{1}{4} [/tex]
[tex] \frac{x - 1}{3} + \frac{2}{1} = \frac{5}{4} [/tex]
[tex] \frac{x - 1 + 6}{3} = \frac{5}{4} [/tex]
[tex] \frac{x - 7}{3} = \frac{5}{4} [/tex]
[tex]x - 7 = \frac{3 \times 5}{4} [/tex]
[tex]x - 7 = \frac{15}{4} [/tex]
[tex]x = \frac{15}{4} \times \frac{7}{1} [/tex]
[tex]x = \frac{105}{4} [/tex]
Sper că te-am ajutat!
