Resuelve las siguientes ecuaciones a) 2 + 3 x = 5x - 6b)3 - 2(x - 5) = 4c)3x + 5(x + 2) = 6(x + 3)d) 2x - (x - 3) = 5(x - 1)?

A) 2 + 3x = 5x - 6

2 + 6 = 5x - 3x

8 = 2x

8 / 2 = x x = 4

b) 3 - 2(x - 5) = 4

3 - 2x + 10 = 4

13 - 4 = 2x

9 / 2 = x

c) 3x + 5(x + 2) = 6(x + 3)

3x + 5x + 10 = 6x + 18

8x - 6x = 18 - 10

2x = 8

x = 8 / 2

x = 4

d) 2x - (x - 3) = 5(x - 1)

2x - x + 3 = 5x - 5

3 + 5 = 5x - 2x + x

8 = 4x

8 / 4 = x

x = 2.
