Question

(x - 4)/2 - (2x + 1)/3 + 2 11/12 = x/6 - 3/4​

Answer 1

Explicație pas cu pas:

$\frac{x - 4}{2} - \frac{2x + 1}{3} + \frac{2 \times 12 + 11}{12} = \frac{x}{6} - \frac{3}{4} \\ \frac{6x - 24 - 8x - 4 + 24 + 11}{12} = \frac{2x - 9}{12} \\ - 2x + 7 = 2x - 9 \\ - 2x - 2x = - 9 - 7 \\ - 4x = - 16 \\ x = \frac{16}{4} = 4$

Answer 2

SALUT

(x-4)/2 - (2x+1)/3 +2 11/12 = x/6 -3/4

x-4/2 -2x+1/3 + 2 1/2 = x/6 -3/4

x-4/2 -2x+1/3 + 5/2 = x/6 -3/4

6(x-4)-4(2x+1)+30 = 2x-9

6x-24-8x-4+30 = 2x-9

-2x+2 = 2x-9

-2x-2x = -9-2

-4x = -11

x=11/4 ≈ 2,75
