=5 1 / 4 + (- 3 1 / 7) + (- 5 1 / 4) + 12 6 / 7
=5 and a quarter + (- 5 and a quarter) + (- 3 - a seventh) + 12 + six seventh
=0-3-1 / 7 + 12 + 6 / 7
=12-3 + 6 / 7 - 1 / 7
=Nine and five out of seven

-35 ÷ (- 7) × (- 1 / 7) - (2 / 3-1 / 12-4 / 15) × (- 60)

Original formula = 5 * (- 1 / 7) + 2 / 3 * 60-1 / 12 * 60-4 / 15 * 60 = - 5 / 7 + 40-5-16 = 19-5 / 7 = 18 and 2 / 7

X is two and one seventh = four and two thirds

X / 15 / 7 = 14 / 3, x = (14 / 3) * (15 / 7) = 10
