Question

the sum of three consecutive integers is 90. Find the three numbers by letting x represent the first integer.

Answer 1

the 3 numbers are CONSECUTIVE
meaning if one is say "x", the next one will be THAT MUCH +/- 1, so it's either less or more than "x" by 1

and the next one after that will be "x" +/- 2

so we could say that

x + (x+1) + (x+2) = 90

# solve for "x"
