Answer:
11, 12, 13
Explanation:
x is the first number
(x + 1) is the second number
(x + 2) is the third number
x + x+1 + x+2 = 36
3x + 3 = 36
3x = 36 - 3
3x = 33
x = 11 ← the first number
the second number = x + 1 = 11 + 1 = 12
the third number = x + 2 = 11 + 2 = 13
First, represent the numbers with variables. is the first number. is the second number, since they are consecutive. is the third and final number.
Make a statement.
Combine the variables.
Combine the constants.
Isolate the variable by subtracting on each side.
Finish isolating the variable by dividing both sides by .
This means the first number is . Since the three numbers are consecutive, the other two numbers are and .
We can then check out work by adding these three numbers together. If they equal , then the answer is correct.
Add and .
This means our answer is correct.
