Question

2x = 6
2 x – 3 = 6 + x
2 ( 2x – 3 ) = 6 + x
4 ( x – 10 ) = - 6 ( 2 – x ) – 6x
2 (x + 1 ) – 3 ( x -2 ) = x – 6 ayuda con esta ecuacion

Answer 1

Explicación paso a paso:

1)

2x = 6

x = 6/2

x = 3

2)

2x - 3 = 6 + x

2x - x = 6 + 3

x = 9

3)

2 × (2x - 3) = 6 + x

4x - 6 = 6 + x

4x - x = 6 + 6

3x = 12

x = 12/3

x = 4

4)

4 × (x - 10) = -6 × (2 - x) - 6x

4x - 40 = -12 + 6x - 6x

4x = -12 + 40

4x = 28

x = 28/4

x = 7

5)

2 × (x + 1) - 3 × (x - 2) = x - 6

2x + 2 - 3x + 6 = x - 6

8 - x = x - 6

8 + 6 = x + x

14 = 2x

14/2 = x

7 = x
