You can put this solution on YOUR website! Charlotte and Edgar's ages add up to 22. Charlotte is one year older than twice Edgar's age. How old are Charlotte and Edgar?
I have to show work with a linear equation.
------
c + e = 22
c = 2e + 1
-------
Substitute for "c" and solve for "e"::
2e+1 + e = 22
3e = 21
Edgar = 7 yrs
-----
Solve for "c"::
c = 2e + 1
c = 2*7+1
Charlotte = 15 yrs
