x+x/3+x-2=26
\n" ); document.write( "2x+x/3=26+2
\n" ); document.write( "(2x*3+x)/3=28
\n" ); document.write( "(6x+x)/3=28
\n" ); document.write( "7x=28*3
\n" ); document.write( "7x=84
\n" ); document.write( "x=84/7
\n" ); document.write( "x=12 ans. for the first side.
\n" ); document.write( "12/3=4 ans. for the second side.
\n" ); document.write( "12-2=10 ans. for the third side.
\n" ); document.write( "Proof:
