Question

2X minus 3/3 + 3X minus 2/2 egal cu 4X + 3/4 - 5 supra doișpe

Answer 1

Răspuns:

x = 2

Explicație pas cu pas:

$\frac{2x - 3}{3} + \frac{3x - 2}{2} = \frac{4x + 3}{4} - \frac{5}{12} \\ \frac{4(2x - 3) + 6(3x - 2)}{12} = \frac{3(4x + 3) - 5}{12} \\ 8x - 12 + 18x - 12 = 12x + 9 - 5 \\ 8x + 18x - 12x = 12 + 12 + 9 - 5 \\ 14x = 28 \\ x = \frac{28}{14} \\ x = 2$
