Answer:
Okay, I'm going to put these as an equation, to make things a bit easier for you.
Let
x
be the bigger number and let
y
be the smaller number.
x
+
y
=
27
x
=
2
y
+
6
Once you see those, it's quite clear that this is a simple substitution problem. So, let's solve for
y
first:
2
y
+
6
+
y
=
27
And then let's substitute it in for the first number:
3
y
+
6
−
6
=
27
−
6
3
y
=
21
y
=
7
And then to solve for
x
:
x
+
7
=
27
x
+
7
−
7
=
27
−
7
x
=
20
