1) 6x + 30 – 5x = 25

2) 3x + 2x = 8x – 15

3) 5.(x - 3) = 4x +16

4) 4.(x – 2) = 2.(x - 10)

ayuda pls

Answer 1

Respuesta:

1) 6x + 30 - 5x =25

6x + 5x = 25 + 30

11x = 55

x= 55 ÷ 11

x= 5

2) 3x + 2x = 8x - 15

5x = 8x - 15

5x + 8x = 15

13x = 15

x = 15 ÷ 13

x = 1,153846154

3) 5(x - 3) = 4x + 16

5x - 5.3 = 4x + 16

5x - 15 = 4x + 16

5x - 4x = 16 + 15

1x = 31

x = 31 ÷ 1

x = 31

4) 4(x - 2) = 2(x - 10)

4x - 4.2 = 2x - 2.10

4x - 8 = 2x - 20

4x + 2x = 20 + 8

6x = 28

x = 28 ÷ 6

x = 4,667
