Answer 1

Resposta:

Explicação passo a passo:

a) 5x+18=33

5x=33-18

5x=15

x=15/5

x=3

b)24y+28=15y-8

24y-15y=-8-28

9y= -36

y= -36/9

y= -4

c) 10x+21-7=10+3x

10x-3x=10-21+7

7x= -4

x= -4/7

x=-0,57

d)52-40=55

Eu não sei onde tá o x kk

e) 432x+14-301=12

432x=12-14+301

432x=299

x= 432/299

x=1,44

f)10x+50+10-2=13

10x=-50-10+2-+13

10x=-45

x=-45/10

x=-4,5

g) 22x+5-3=24

22x=24-5+3

22x=19+3

22x=22

x=22/22

x=1

h)12x-4,6=12

12x=12+4,6

12x=16,6

x=16,6/12

x=1,38

i) 4x+2+36=10

4x=-36-2+10

4x=-28

x=-28/4

x=-7

j) 10x-25=47

10x=47+25

10x=72

x=72/10

x=7,2

ESPERO TER AJUDADO!!!
