C ) 3 X = 15

D ) 2 X = 10

E ) 3 X = - 9

F ) 2 X -2 = 12 -5 X

G ) 3 X - 13 = 8

H ) 4 X - 9 = 23

I ) 7 X - 33 = - 12


J ) 33 + X = 5 - 3 X

K) 2 X = - 21

L ) 7 X = - 21

Answer 1

A) X - 1 = 5

x-1=5

x=5+1

x=6

B) X - 1 = 5

x-1=5

x=5+1

x=6

C ) 3 X = 15

3x=15

x=15/3

x=5

D ) 2 X = 10

2x=10

x=10/2

x=5

E ) 3 X = - 9

3x=-9

x=-9/3

x=-3

F ) 2X -2 = 12 -5X

2x-2=12-5x

2x+5x=12+2

7x=14

x=14/7

x=2

G ) 3 X - 13 = 8

3x=8+13

3x=21

x=21/3

x=7

H ) 4 X - 9 = 23

4x-9=23

4x=23+9

4x=32

x=32/4

x=8

I ) 7 X - 33 = - 12

7x-33=-12

7x=-12+33

7x=21

x=21/7

x=3

J ) 33 + X = 5 - 3 X

33+x=5-3x

x+3x=5-33

4x=28

x=28/4

x=7

K) 2 X = - 21

2x=-21

x=-21/2

L ) 7 X = - 21

7x=-21

x=-21/7

x=-3

M) 4 X =- 12

4x=-12

x=-12/4

x=-3

N) 35 X = - 105

35x=-105

x=-105/35

x=-3

espero ter ajudado!

boa tarde!
