2x - 2 = 2(x - 1)7(2x + 1 = 14x6(7 - x) = 8(6 - x)me pueden aayudar estos ejercicios pliss?

2X - 2 = 2(X - 1)

2X - 2 = 2X - 2

2X - 2 - 2X + 2 = 0

0 = 0 - - - - - - - - - - - - - - - - -

7(2X + 1) = 14X

14X + 7 = 14X

14X + 7 - 14X = 0

7 = 0 - - - - - - - - - - - - - - - - - - -

6(7 - X) = 8(6 - X)

42 - 6X = 48 - 8x

42 - 6x - 48 + 8x = 0

2x - 6 = 0

2x = 6

x = 6 / 2

x = 3 - - - - - - - - - - - - - -.
