Answer 1

Explicação passo-a-passo:

a) 5x+18=33

5x=33-18

5x=33-18

x=15/5= 3

b)3x+14-5=0

3x=0-14+5

3x=-9

x=-9/3 =-3

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

10x-3x=10-21+7

7x=-11+7

x= -4/7

d)5x-40=55

5x=55+40

5x=96

x=96/5=19

e)10x-2+10=2+6x

10x-6x=2+2-10

4x=-6

x=-6/4

f)5x-40=2-c

5x=2-c+40

5x=42-c

x=42/5-1/5c

g)20+6x=-2x+26

6x+2x=26-20

8x=6

x=6/8

H) 35x+1=3+31x

35x-31x=3-1

4x=2

x=2/4 (÷2)

x=1/2

Espero ter ajudado :D.
