Question

find three consecutive positive even integer whose sum is 19

Answer 1

Here we will use algebra to find three consecutive integers whose sum is 19.

We assign X to the first integer. Since they are consecutive, it means that the 2nd number will be X+1 and the third number will be X+2 and they should all add up to 19. Therefore, you can write the equation as follows:

X + X + 1 + X + 2 = 19
