( Si no sabes no respondas)
Como las [puedo resolver?
1. 44=t−72
2. 18+z=40
3.18−(−f)=91
4. −57=y−2
5. 14=d+(−10)

Answer 1

44 = t - 72

44 + 72 = t

116 = t

18 + z = 40

z = 40 - 18

z = 22

18 - (-f) = 91

18 + f = 91

f = 91 - 18

f = 73

-57 = y - 2

- 57 - 2 = y

59 = y

14 = d + (-10)

14 = d - 10

14 + 10 = d

24 = d
