Question

Ayudadme pls, son ecuaciones por favor dadme el problema completo pls

Answer 1

Respuesta:

a)

2x + 2x + 2x = 600

6x = 600

x = 100

b)

2(3x + 5) + 2(3x - 1) = 54cm

6x + 10 + 6x - 2

12x = 54 -10 + 2

12x = 46

x = 3

c)

4(x + 4) = 48cm

4x + 16 = 48

4x = 48 - 16

4x = 32

x = 8

d)

2x + 3x + 1 + 2(x)= 36

2x + 3x + 1 + 2x= 36

7x = 36 - 1

7x = 35

x = 5

e)

x + 4x - 3 + 3x + 3 = 56

8x = 56

x = 7
