For argument sake S- Shannon

                               T- Tony

                               J- Jeanette

                               N- Nicholas

75= 5+T+2xS+2xJ

The actual equation would be

5+x+2x+2x=75

5+5x=75

subrtract 5 from each side

5x=70

divide each side by 5

x=14

If x represents T (Tony) he is 14 which would make shannons equation

14+5=19

Shannon is 19
