A) X + 5 = 12
F) X + 12 = 32
J) 2X = 10
K) 6X = 54
B) X-4 = 6
G) X- 8 = 12
C) 2X = 16
H) X-5 = 40
L) 7X = 49
D) 3X = 21
1) 5X = 35
M) 8X = 48
E) X + 9 = 20​

Answer 1

Explicação passo-a-passo:

A) X + 5 = 12

X = 12 - 5

X = 7

F) X + 12 = 32

X = 32 - 12

X = 20

J) 2X = 10

X = 10/2

X = 5

K) 6X = 54

X = 54/6

X = 9

B) X-4 = 6

X = 6 + 4

X = 10

G) X- 8 = 12

X = 12 + 8

X = 20

C) 2X = 16

X = 16/2

X = 8

H) X-5 = 40

X = 40 + 5

X = 45

L) 7X = 49

X = 49/7

X = 7

D) 3X = 21

X = 21/3

X = 7

1) 5X = 35

X = 35/5

X = 7

M) 8X = 48

X = 48/8

X = 6

E) X + 9 = 20

X = 20 - 9

X = 11
