х = - 9.4
Пошаговое объяснение:
х = 1.8 × (- 4 2/3) + 6 5/6 × (- 6/41)
х = 18/10 × - 4 2/3 + 6 5/6 × - 6/41
х = (18/10 × - 14/3) + (41/6 × - 6/41)
х = (- 6 × 14/10) + (- 1/1)
х = (- 84/10) + (- 1)
х = - 8.4 - 1
х = - 9.4
x = 1.8(- 4 2/3) + 6 5/6 * (- 6/41)
х=1 8/10*(-4 2/3) + 6 5/6*(-6/41)
х=18/10*(-14/3)+
х=-8 2/5+41/6*(-6/41)
х=-8 2/5-1
х=-9 2/5
