Question

Urgente me ajudaaaaaaaaaaaaaaaaaaa pela amor de Deus

Answer 1

a) x= 22+ 18
x= 40

b) 3x= -10
x= -10/3

c)4x+5= 3x- 19
4x-3x=-19-5
x= -24

d)6x = 66
x= 66/6
x= 11

e)

Answer 2

a ) x - 18 = 22

x = 22 + 18

x = 40

b) 3x = -10

x = - 10 / 3

x = - 3,3

c) 4x + 5 = 3x - 19

4x - 3x = -19 - 5

x = - 24

d) 6x = 66

x = 66 / 6

x = 11

e) 3 (x + 2) + 5 = x + 12

3x + 6 + 5 = x + 12

3x - x = 12 - 6 - 5

2x = 1

x = 1 / 2

f ) x + 4 (x - 1) = 23 - 2 (x + 3)

x + 4x - 4 = 23 - 2x - 6

5x + 2x = 23 - 6 + 4

7x = 23 - 2

7x = 21

x = 21 / 3

x = 7

g) 7 (x - 1) = 2 (3x + 1)

7x - 7 = 6x + 2

7x - 6x = 2 + 7

x = 9

---------------------------------------------------------------------------------------------------------------

Questão 2

3x + 4 = 26

3x = 26 - 4

3x = 22

x = 22/3

Questão 3

5x - 5 = 25

5x = 25 + 5

5x = 30

x = 30 / 5

x = 6 meninas

Questão 4

2x - x  = 90 + 65

x = 155
