Answer:

2 + x = 5

2 + x = 5 x + 1 = 4

2 + x = 5 x + 1 = 4 - 5 + x = - 2

Explanation:

2 + x = 5

2 + x = 5 x = 5 - 2

2x = 3

2x = 3x + 1 = 4

2x = 3x + 1 = 4 x = 4 - 1

2x = 3x + 1 = 4 x = 4 - 1x = 3

2x = 3x + 1 = 4 x = 4 - 1x = 3- 5 + x = - 2

2x = 3x + 1 = 4 x = 4 - 1x = 3- 5 + x = - 2x = -2 + 5

2x = 3x + 1 = 4 x = 4 - 1x = 3- 5 + x = - 2x = -2 + 5 x = 3
