En resumen

2x + x = 12. 2(x - 3) - 4 = 3 3x = 12. 2x - 6 - 4 = 3 x = 12 : 3. 2x = 3 + 5 + 4 x = 4. 2x = 12 x = 12 : 2 x + 3 + 2x - 1 = 8. X = 6 x + 2x = 8 - 3 + 1 3x = 5 + 1 3x = 6 x = 6 : 3 x = 2.

2x + x = 12.

2(x - 3) - 4 = 3

3x = 12.

2x - 6 - 4 = 3

x = 12 : 3.

2x = 3 + 5 + 4

x = 4.

2x = 12 x = 12 : 2

x + 3 + 2x - 1 = 8.

X = 6

x + 2x = 8 - 3 + 1

3x = 5 + 1

3x = 6

x = 6 : 3

x = 2.
