You can put this solution on YOUR website!
y = 3x + 7
\n" ); document.write( "Substituting h for x
\n" ); document.write( "Substituting h + 15 for y
\n" ); document.write( "h + 15 = 3(h) + 7
\n" ); document.write( "h + 15 = 3h + 7
\n" ); document.write( " -2h = -8
\n" ); document.write( " h = 4
\n" ); document.write( "x = 4
\n" ); document.write( "y = 19
\n" ); document.write( "Hope this helps.
