\n" ); document.write( "
Let Roy's, and Kayla's ages be R and K, respectively
\n" );
document.write( "Then K + R = 91_____K = 91 - R ----- eq (i)
\n" );
document.write( "Also, R - 8 = 4(K - 8)______R - 8 = 4K - 32______R = 4K - 24 ------ eq (ii)
\n" );
document.write( "R = 4(91 - R) - 24 ----- Substituting 91 - R for K in eq (ii)
\n" );
document.write( "R = 364 - 4R - 24
\n" );
document.write( "R + 4R = 364 - 24
\n" );
document.write( "5R = 340
\n" );
document.write( "Roy's age, or \"highlight_green%28matrix%281%2C5%2C+R%2C+%22=%22%2C+340%2F5%2C+%22=%22%2C+68%29%29\" \n" );
