The numbers you are looking for are 5 and 17. I worked this out by using the following equation.

The first number = x

The other number is 3x+2 in that case, because it is 3 times x plus 2.

x+2+x=22 we add these together knowing that they are equal to 22.

4x+2=22 we then subtract 2 from both sides.

4x=20 Now we divide both sides by 4.

x=5 Which gives us our first number =5.

Okay, so now we need to find the second number:

3x+2= ? Substitute 5 (the answer from the first part) for x.

3(5)+2=

15+2= 17 Therefore, the 2nd number is 17.

Algebra looks very complicated on the surface, but it gets easier once you understand the methods that are used.

I have included a video that might be helpful (pay no attention to the "for dummies" reference, it's just for beginners).

Once you have the basics, you can work anything out!
