100,000,000 + 50,000,000 + 3,000,000 + 400,000 + 700 + 80
You'll need to create two equations and have a 'system of equations' then use direct substitution to turn the equation into one. Whichever equation is easiest to solve for x or y. Solve that one for x or y and plug the result in for the variable in the other equation. Then you will have an equation with only 1 unknown.
Subsitute 100 for n
a100=100/(100+1)=100/101
