Answer:
The number is 13
Explanation:
Let the number be y
1 is subtracted from the number. This can be written as:
y – 1
The difference is tripled. This can be written as:
3(y – 1)
The result of the difference tripled is 23 more than the number. This can be written as:
3(y – 1) = 23 + y
Thus, we can obtain the value of y as follow:
3(y – 1) = 23 + y
Clear bracket
3y – 3 = 23 + y
Collect like terms
3y – y = 23 + 3
2y = 26
Divide both side by 2
y = 26 / 2
y = 13
Thus, the number is 13.
