Answer:
1
Step-by-step explanation:
Let the number be X
condition
12 more than seven times the number
it can be represented numerically by using process given belwo
seven times the number will be 7 * X = 7X
12 more than 7X will be equal to 7X + 12
______________________________
This number (7X + 12) is equal to number plus 19
number plus 18 will be X + 18
therefore according to the question
7X + 12 = X + 18
=> 7X - X = 18 - 12
=> 6X = 6
=> X = 6/6 = 1 (Answer)
The number is 1.
