Question

One increased by 7 times a number is the same as 5 times the number plus 25

Answer 1

12

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
