\n" ); document.write( "Let known of the following:
\n" ); document.write( " $\"x\"$ = Greg's age
\n" ); document.write( " $\"x%2B30\"$ = Greg's father's age
\n" ); document.write( "Then in 15 yrs,
\n" ); document.write( " $\"x%2Bhighlight%2815yrs%29%2Bx%2B30%2Bhighlight%2815yrs%29=130yrs\"$ , working eqn
\n" ); document.write( " $\"2x%2B60=130\"$
\n" ); document.write( " $\"2x=130-60=70\"$ -------> $\"cross%282%29x%2Fcross%282%29=cross%2870%2935%2Fcross%282%29\"$
\n" ); document.write( " $\"highlight%28x=35yrs%29\"$ , Greg's age
\n" ); document.write( " $\"35%2B30=highlight%2865%29\"$ , greg's father's age
\n" ); document.write( "In doubt? Let's go back working eqn:
\n" ); document.write( " $\"35%2B15%2B65%2B15=130\"$
\n" ); document.write( " $\"130yrs=130yrs\"$
\n" ); document.write( "Thank you,
