You can put this solution on YOUR website!
-9w + 17 = 7 - 4w
\n" ); document.write( "we want to get unknown on the left and the numerical values on the right
\n" ); document.write( "Add 4w to both sides, results
\n" ); document.write( "-9w + 4w + 17 = 7
\n" ); document.write( ":
\n" ); document.write( "Subtract 17 from both sides, results:
\n" ); document.write( "-9w + 4w = 7 - 17
\n" ); document.write( ";
\n" ); document.write( "combine like terms
\n" ); document.write( "-5w = -10
\n" ); document.write( ";
\n" ); document.write( "The variable always has to be positive, multiply both sides by -1
\n" ); document.write( "5w = +10
\n" ); document.write( "divide both sides by 5
\n" ); document.write( "w = \"10%2F5\"
\n" ); document.write( "w = 2
\n" ); document.write( ":

\n" ); document.write( "-9w + 17 = 7 - 4w
\n" ); document.write( "-9(2) + 17 = 7 - 4(2)
\n" ); document.write( "-18 + 17 = 7 - 8
\n" ); document.write( "-1 = -1; confirms our solution
\n" ); document.write( " \n" ); document.write( "
