Answer:

The Number is 5.

Explanation:

let the number be x.

Expression for Sum of thirteen and twice a number = 2 × x + 13

Expression for Seven less than six times a number = 6 × x - 7

Now, According to the question both expressions are equal

2 × x + 13 = 6 × x - 7

2x + 13 = 6x - 7

2x + 13 - 6x = -7

2x -6x + 13 = -7

-4x + 13 = -7

-4x = -7 - 13

-4x = -20

x = -20/(-4)

x = 5

Therefore, The Number is 5
