Question

resolva as equações:
9x – 4 = 32:

26 x – 22 = 30x + 42:

17x – 34 = 0:

4x + 4 = 20:

6x + 12 = 3x – 3:

2x – 8 = - 4x + 10:

2 . (x + 4) – (x – 5) = 4. (3 – x):

6 .(2x + 4) = 2. (3x + 6):

2. (x + 2) + 3. (x + 2) = 5.(2 – x):

x - (6+x)/3 = 1/3 .((x-14)/2) :

x + (8+4x )/5= 1/5.((x+3)/2):

x/3+ ((x-4)/2)+ 2x/3= x/2+ 3x/2-(x+4):

Answer 1

Resposta  

so a primeira

Explicação passo-a-passo:

9x - 4 = 32

9x = +4 +32

9x = 36

x = 36:9

x =  4

17x - 34 = 0

17x = 34

x = 34:17

x = 2

4x = 20 - 4

4x = 16

x = 16:4

x = 4

2x + 4 + 3x + 6 = 20 - 5x

2x + 3x + 5x = 20 - 6 -4

10x = 10

x = 10:10

x = 1
