Question

EJERCICIO (4) Resolver y verificar las siguientes ecuaciones:

3(x++2) = 18
4x + 2(x + 3) = 2(x + 2)
6 + 2(x + 1) = 2
3(2x-1)+2(1-2x)=5 5x − (1-x) = 3x - 1
2(1-x) - 3 = 3(2x + 1) + 20​

Answer 1

EJERCICIO 1 )

3(x+2) = 18

3x + 6 = 18

3x = 18 - 6

3x = 12

x = 12/3

x = 4

EJERCICIO 2)

4x + 2(x + 3) = 2(x+2)

4x + 2x + 6 = 2x + 4

6x + 6 = 2x + 4

6x - 2x= 4 - 6

4x = -2

x = -2/4

x = -0.5
