Por favooor, me ajudem com essa atividade é pra entregar hj!!

Answer 1

Resposta:

1)

A) x+10 = 35 ---> x = 25

B) x-10 = 16 ---> x = 26

C) 2x+10 = 40 ---> x = 15

D) 3x+15 = 45 ---> x = 10

E) 4x+20 = 60 ---> x = 10

F) 2x+5 = x-15 ---> x = -20

G) 3x+8 = x+18 ---> x = 5

H) x/2-6 = 16 ---> x = 44

I) x/3+3 = 13 ---> x = 30

J) 4x+10 = 2x+30 ---> x = 10

Explicação passo a passo:

Resolução:

1)

A)

x+10 = 35

x = 35-10

x = 25

B)

x-10 = 16

x = 16+10

x = 26

C)

2x+10 = 40

2x = 40-10

2x = 30

x = 30/2

x = 15

D)

3x+15 = 45

3x = 45-15

3x = 30

x = 30/3

x = 10

E)

4x+20 = 60

4x = 60-20

4x = 40

x = 40/4

x = 10

__________________________________

F)

2x+5 = x-15

2x-x = -15-5

x = -20

G)

3x+8 = x+18

3x-x = 18-8

2x = 10

x = 10/2

x = 5

__________________________________

H)

x/2-6 = 16

2×(x/2-6) = 2×16

2x/2-12 = 32

x-12 = 32

x = 32+12

x = 44

__________________________________

I)

x/3+3 = 13

3×(x/3+3) = 3×13

3x/3+9 = 39

x+9 = 39

x = 39-9

x = 30

__________________________________

J)

4x+10 = 2x+30

4x-2x = 30-10

2x = 20

x = 20/2

x = 10

Eu espero ter ajudado :)

Answer 2

Explicação passo-a-passo:

1]A)x+10=35 F)2x+5=xote

x=35-10 2x-x=-15-5

X=25 X=-20

B)x-10=16 G)3x+8=x+18

x=16+10 3x-x=18-8

X=26 2x=10

x=10/2

X=5

C)2x+10=40 H)x/2-6=16

2x=40-10 x/2=16+6

x=30/2 x=22×2

X=15 X=44

D)3x+15=45 I)x/3+3=13

3x=45-15 x/3=13-3

x=30/3 x=10×3

X=10 X=30

E)4x+20=60 J)4x+10=2x+30

4x=60-20 4x-2x=30-10

x=40/4 2x=20

X=10 x=20/2

X=10

Espero ter ajudado! Bons estudos:)
