A total of $20,000 is to be invested, some in bonds and some in certficates of deposit (CDs). If the amount invested in bonds is to exceed that in CDs by $2000, how much will be invested in each type of instrument?
Let C = the amount invested in CDs
then the amount invested in bonds will be C+2000.
From this information an equation can now be written

or in words the amount invest in CDs plus the amount invested in bonds equals 20000.
This equation can be written as
Subtracting 2000 from both sides you get
Dividing both sides by 2 you get
Therefore the amount invested in CDs is $9000 and the amount invested in bonds is $2000 more or $11000.
