M = A+4
\n" ); document.write( "3M = 5A and since we just said that M = A+4, substitute for M:
\n" ); document.write( "3(A+4) = 5A
\n" ); document.write( "3A+12 = 5A Subtract 12 and 5A on both sides:
\n" ); document.write( "-2A = -12 Divide both sides by -2 and remember -/- = +
\n" ); document.write( "A = 6 Andrew is 6
\n" ); document.write( "M = A+4 = 6+4 = 10 Mike is 10
\n" ); document.write( "
\n" );
