Answer:

12

Step-by-step explanation:

Let the number = x

7x + 1 = 5x + 25                 Subtract 5x from both sides.

7x - 5x + 1 = 5x - 5x + 25   Combine

2x + 1 = 25                          Subtract 1 from both sides.

2x + 1 - 1 = 25-1                   Combine

2x = 24                               Divide by 2

2x/2 = 24/2

x = 12
