Answer:

Step-by-step explanation:

It would be answer b, because if you were to solve this, then this is how you would do it (in the most effecient way):

2.5x + 1.2 = 1.2x + 4.2

2.5x + 1.2 - 1.2 = 1.2x + 4.2 - 1.2

2.5x = 1.2x + 3

2.5x - 1.2x = 1.2x - 1.2x + 3

1.3x = 3

1.3x/1.3 = 3/1.3

x = 3/1.3
