You can put this solution on YOUR website! NOW, I=me,,,,S=Sue
.
Future (I+x) =S,,,(S+x)= I+4,,,,,,or S=(I-x+4)
.
S=I+x = I-x+4
.
2x =4
.
x=2
.
checking: Let I=10,,,Future I = 10+2 =12
,,,,,,,,,,,,,,Future Sue = S+2 = I+4 = 10+4=14,,,,S = 12
Again Now I=10,,,,S=12
Future,,,,,,I=12,,,,S=14,,,,,,,,checks (10+4)
.
In short,,,Sue is 2 yrs older than I
