You can put this solution on YOUR website!
Francisco = x
Oriana = x+5
Sum of ages is 27
so
%28x%29%2B%28x%2B5%29=27
now solve for x
%28x%29%2B%28x%2B5%29=27
x%2Bx%2B5=27 simplify
2x%2B5=27 combine like terms
2x=27-5 isolate term with x
2x=22 divide both sides by 2
x=11
Now that you have solved for x you know Francisco is 11
use that to find Oriana's age.
