We have,

2(x-1/8) - 3/5 x = 55/4

Step 1 :

2x - 1/4 - 3/5 x = 55/4

Step 2 :

7/5x - 1/4 = 55/4

Step 3 :

7/5x - 1/4 + 1/4 = 55/4 + 1/4

7/5x = 56/4

Step 4:

x = 10

 

Hence, Rahul used the addition property of equality in Step 3.

As per question

Rahul solved the equation 2(x – 1/8)-3/5x=55/4

2x-2/8-3/5x=55/4

2x- 3/5x=55/4+2/8

(10x-3x)/5=(110+2)/8

7x/5=112/8

7x=5*14

x=70/7

x=10
