Answer 1

Resposta:

a) x=20-2

x=18

b- x=120+5

x=125

c- x=21-3

x=18

d- x=498-129=369

e- x=85-7

x=78

f- y=9+35

y=44

g- x= 22/2

x= 11

h- x=12/3

x= 4

i- x= 125/5

x=25

j- .-2x= -12 *-1

2x= 12

x= 12/2

k. 3x= 5+16

3x=21

x= 21/3

x=7

l- 2x=8+10

2x= 18

x=18/2

x=9

m- x= 5+16-10

x=11

n- x=7+6-12

x=13-12

x= 1
