5x+1=3x+1

6x-1=11

x-1=7 (x-1)

x-2=1+4x

5x+5=5 (x-1)

5x + 1 = 3x + 1

5x-3x = 1-1

2x = 0

x = 0

6x - 1 = 11

6x = 11+1

6x = 12

х = 12:6

x = 2.

x - 1 = 7 (x-1)

x - 1 = 7x - 7

x - 7x = - 7 + 1

- 6 x = - 6

x = - 6: (-6)

x = 1.

x - 2 = 1+4x

x - 4x = 1 + 2

- 3 x = 3

x = 3 : (-3)

x = - 1.

5x+5 = 5 (x-1)

5x + 5 = 5 x - 5

5 x - 5x = - 5 - 5

0 = - 5 - 5

0 = - 10

Утверждение ложно для любого значения х
