Here we will use algebra to find three consecutive integers whose sum is 847. We start by assigning X to the first integer. Since they are consecutive, it means that the 2nd number will be X + 1 and the 3rd number will be X + 2 and they should all add up to 847. Therefore, you can write the equation as follows:
(X) + (X + 1) + (X + 2) = 847
To solve for X, you first add the integers together and the X variables together. Then you subtract three from each side, followed by dividing by 3 on each side. Here is the work to show our math:
X + X + 1 + X + 2 = 847
3X + 3 = 847
3X + 3 - 3 = 847 - 3
3X = 844
3X/3 = 844/3
X = 281 1/3
Since 281 1/3 is not an integer, there is no true answer to this problem.
However, there are three numbers that add up to 847. The first number is (281 1/3), the second number is (281 1/3) + 1, and the third number is (281 1/3) + 2. Therefore, we could make this the answer to "Three consecutive numbers that add up to 847 are?":
281 1/3 + 282 1/3 + 283 1/3 = 847
