D)5x = 36 + 2x

E)4x = 54 – 5x

F)5x = – 35

G)7x + 50 = 30 + 6x


H)4x – 18 = 32 – x

i) 3x = 9

5

J)4x = 12

6 2
​

Answer 1

Resposta:

Explicação passo a passo:

C)x + 23 = 52

X = 52 - 23

X = 29

________

D)5x = 36 + 2x

5x - 2x = 36

3x = 36

X = 36/3

X = 12

_______

E)4x = 54 – 5x

4x+5x = 54

9x = 54

X = 54/9

X = 6

______

F)5x = – 35

X = - 35/5

x = - 7

_______

G)7x + 50 = 30 + 6x

7x - 6x = 30 - 50

x = - 20

_________

H)4x – 18 = 32 – x

4x + x = 32+18

5x = 50

X = 50/5

X = 10

__________

i) 3x = 9

5

3x/5 = 9

3x = 5.9

3x = 45

X = 45/3

X = 15

________

J)4x = 12

6 2

4x/6 = 12/2

2x/3 = 6

2x = 3.6

2x = 18

X = 18/2

X = 9
