Answer 1

Resposta:

Explicação passo-a-passo:

a) x+12=34

x=34-12

x=22

b) X-22=36

x=36+22

x=58

c)X+50=100

x=100-50

x=50

d) X-36=52

x=52+36

x=88

e)X+74=85

x=85-74

x=11

h) X-8=59

x=59+8

x=67

f) X-123=80

x=80+123

x=203

g)X+5=40

x=40-5

x=35

1) X-335=520

x=520+335

x=855

i)X+37=51

x=51-37

x=14

j) X-29=86

x=86+29

x=115

k)X+252=128

x=128-252

x=-124

l)X-335=520​

x=520+335

x=855
