Explanation

2x + 5 = 13

Step 2: Divide both sides by 2  

x = 8 / 2  

x = 4

Explanation

1 dozen eggs = 12 eggs, costing Rs. 250.

Cost per egg =  250/12 Rs.

For 30 eggs, the cost =  30 × 250/12 = 250

​Let's calculate it:

Cost for 30 eggs = 30 × 250/ 12 = 30 × 20.83 = 625

Cost for 30 eggs =30×20.83=625

So, the cost price of 30 eggs is Rs. 625.
