Question

25700+х =37536 ,20*17+х =56782 ,14:2+х =134 ,х +13+12=54

Answer 1

25700 + x = 37536

x = 37536 - 25700

x = 11836

25700 + 11836 = 37536

37536 = 37536


20 × 17 + x = 56782

340 + x = 56782

x = 56782 - 340

x = 56442

20 × 17 + 56442 = 56782

56782 = 56782


14 ÷ 2 + x = 134

7 + x = 134

x = 134 - 7

x = 127

14 ÷ 2 + 127 = 134

134 = 134


x + 13 + 12 = 54

x + 25 = 54

x = 54 - 25

x = 29

29 + 13 + 12 = 54

54 = 54
