You can put this solution on YOUR website! barbra is 5 years older than Roxanne. in 6 years, the sum of their ages will be 35 years .how old is each person now
-----------------------
Equation:
b = r + 5
b + 6 + r + 6 = 35
-----
Substitute for "b" and solve for "r"::
r + 11 + r + 6 = 35
2r + 17 = 35
r = 9 yrs (Rosanne's age now)
b = r+5 = 14 yrs (Barbara's age now)
