Resuelve a) 5x - 2 + 2x = 6x + 8 b)4x + 3x - 2x = 45 c) - x + 4x - 3 = 5 - 2x?

Resuelve a) 5x - 2 + 2x = 6x + 8 b)4x + 3x - 2x = 45 c) - x + 4x - 3 = 5 - 2x.

En resumen

A) 5x - 2 + 2x = 6x + 8 5x + 2x - 6x = 8 + 2 x = 10 b) 4x + 3x - 2x = 45 5x = 45 x = 45 / 5 x = 9 c) - x + 4x - 3 = 5 - 2x - x + 4x + 2x = 5 + 3 5x = 8 x = 8 / 5.

A)

5x - 2 + 2x = 6x + 8

5x + 2x - 6x = 8 + 2

x = 10

b)

4x + 3x - 2x = 45

5x = 45

x = 45 / 5

x = 9

c) - x + 4x - 3 = 5 - 2x - x + 4x + 2x = 5 + 3

5x = 8

x = 8 / 5.
