You can put this solution on YOUR website!
1) Prove that if 3/5 x =-9, then x=-15.
\n" ); document.write( "You can solve the eqn for x, or sub -15 for x.
\n" ); document.write( "(3/5)*-15 = -9
\n" ); document.write( "-9 = -9
\n" ); document.write( "----------------
\n" ); document.write( "Do the others the same way.
\n" ); document.write( "2) Prove that if 3x-2=x-8, then x=-3.\r
\n" ); document.write( "\n" ); document.write( "3) Prove that if 2(x-3)=8, then x=7.\r
\n" ); document.write( "\n" ); document.write( "4) Prove that if 3x-4=1/2 x +6, then x=4.\r
\n" ); document.write( "\n" ); document.write( "5) If x=y+3 and y+3=10, then x=10.
\n" ); document.write( "
\n" );
