If a o b is defined to be 2a-3b and 5 o x = 1, then x = ?\r
\n" ); document.write( "\n" ); document.write( "The answer is 3. Why?
\n" ); document.write( "

\r\n" );
document.write( "a o b = 2*a - 3*b\r\n" );
document.write( "\r\n" );
document.write( "Substitute 5 for a and x for b\r\n" );
document.write( "\r\n" );
document.write( "a o b = 2*a - 3*b\r\n" );
document.write( "5 o x = 2*5 - 3*x\r\n" );
document.write( "\r\n" );
document.write( "We are told that this equals 1, so\r\n" );
document.write( "\r\n" );
document.write( "5 o x = 2*5 - 3*x =  1\r\n" );
document.write( "          10 - 3x =  1\r\n" );
document.write( "              -3x = -9\r\n" );

document.write( "5 o x = 2*5 - 3*x\r\n" );
document.write( "5 o 3 = 2*5 - 3*3 = 10 - 9 = 1\r\n" );
