Hint:

Let x = amount invested in bonds and y = amount invested in CDs


So if "A total of $28,000 is to be invested", then x%2By=28000, which is the first equation


and "If the amount invested in bonds is to exceed that in CDs by $7000", then x=y%2B7000



Now plug x=y%2B7000 into the first equation to get


x%2By=28000


y%2B7000%2By=28000


From here, solve for y. Once you have a solution for y, use it to find x.
