Question

Daca x+2\3=-1\2 rpt va roggg❤❤

Answer 1

x + 2 / 3 = - 1 / 2

x = - 1 / 2 - 2 / 3

x = - 3 / 6 - 4 / 6

x = ( - 3 - 4 ) / 6

x = - 7 / 6

Verific: - 7 / 6 + 2 / 3 = - 7 / 6 + 4 / 6 = - 3 / 6 = - 1 / 2

Answer 2

$x + \frac{2}{3} = - \frac{1}{2} \\ \\ x = - \frac{2}{3} - \frac{1}{2} \\ \\ x = - \frac{2}{3} \times \frac{2}{2} - \frac{1}{2} \\ \\ x = - \frac{2}{3} \times \frac{2}{2} - \frac{1}{2} \times \frac{3}{3} \\ \\ x = - \frac{2 \times 2}{3 \times 2} - \frac{1}{2} \times \frac{3}{3} \\ \\ x = - \frac{2 \times 2}{6} - \frac{1}{2} \times \frac{3}{3} \\ \\ x = - \frac{2 \times 2}{6} - \frac{1 \times 3}{2 \times 3} \\ \\ x = - \frac{2 \times 2}{6} - \frac{1 \times 3}{6} \\ \\ x = \frac{ - (2 \times 2) - (1 \times 3)}{6} \\ \\ x = \frac{ - 4 - 3}{6} = \frac{ - 7}{6} =- \frac{7}{6}$
