Answer:

The correct answer is option 2

Subtract 6.4 from the each side of equation

Step-by-step explanation:

The given equation,

3.5n  + 6.4 = 42.5

To solve the equation

3.5n  + 6.4 = 42.5

Step 1: Subtract 6.4 from the both side

3.5n  + 6.4 - 6.4 = 42.5 - 6.4

3.5n = 36.1

Step 2:  Divide both side by 3.5

3.5n/3.5 = 36.1/3.5

n = 10.34

Therefore the correct answer is option 2
