  • Even Integer Pattern: n, n + 2, n + 4, n + 6, etc.
  • Let x = smaller integer

So firstly, our two integers are x and x + 2. And we know that the sum of the smaller integer, x, and 3 times the larger integer, x + 2, is 150. Using what we know, our equation is
x+3(x+2)=150

Firstly, foil 3(x + 2):
x+3x+6=150

Next, combine like terms:
4x+6=150

Next, subtract 6 on both sides:
4x=144

And lastly, divide 4 on both sides and your answer will be
x=36

Now since we know that the smaller integer is 36, add 2 to 36 to get the larger integer, which is 38.

In short, the smaller integer is 36 and the larger integer is 38.
