Teacher 1=4x
\n" ); document.write( "Teacher 2=x
\n" ); document.write( "2(x+6)=4x+6
\n" ); document.write( "2x+12=4x+6
\n" ); document.write( "2x-4x=6-12
\n" ); document.write( "-2x=-6
\n" ); document.write( "x=-6/-2
\n" ); document.write( "x=3 years experience for Teacher 2.
\n" ); document.write( "4*3=12 years experience for teacher 1.
\n" ); document.write( "Proof:
\n" ); document.write( "2(3+6)=4*3+6
\n" ); document.write( "2*9=12+6
