Answer 1

Resposta:

a) 3+x=0

x = 0-3

x = -3

b) 23X + 2 = 0

23x = -2 + 0

x = -2/23

c) - 7 + 4X=25

4x = 25 + 7

x = 32/4

x = 8

d) 5x - 3x = 30

2x = 30

x = 30/2

x = 15

e) 4x + 10 = 45 - 3X

4x + 3x = 45 - 10

7x = 35

x = 35/7

x = 5

f) 2x + 4 = 2 - 3X

2x + 3x = 2 - 4

5x = -2

x = -2/5

D) 11 + 2x + 3 = -5X + 2 + X

14 + 2x = - 4x + 2

2x + 4x = 2 - 14

6x = - 12

x = - 12/6

x = - 6

1) 7 (x - 2) = 5(X+3)

7x - 14 = 5x + 15

7x - 5x = 15 + 14

2x = 29

x = 29/2

m) 2 (3x - 5) - X = 10 - 3X

6x - 10 - x = 10 - 3x

5x + 3x = 10 + 10

8x = 20

x = 20/8

x = 5/2

n) 2 (X-6) = - 3 (5 + X)

2x - 12 = -15 - 3x

2x + 3x = -15 + 12

5x = -3

x = -3/5

3 (X + 10) - 2 (X - 5) = 0

3x + 30 - 2x - 10 = 0

x +20 = 0

x = -20

p)7(x - 1) - 2 (X - 5) = X - 5

7x - 7 - 2x + 10 = x - 5

5x + 3 = x - 5

5x - x = -5 - 3

4x = -8

x = -8/4

x = - 2
