You can put this solution on YOUR website!
Given:
\n" ); document.write( ".
\n" ); document.write( "4x-6y=-30
\n" ); document.write( ".
\n" ); document.write( "To write this as a function of x, solve for y and then replace y with f(x).
\n" ); document.write( ".
\n" ); document.write( "Begin by getting the term containing y by itself on the left side. To get rid of the 4x
\n" ); document.write( "term on the left side, subtract 4x (or add negative 4x) to both sides. When you do that
\n" ); document.write( "you get:
\n" ); document.write( ".
\n" ); document.write( " $\"-6y+=+-+4x+-+30\"$
\n" ); document.write( ".
\n" ); document.write( "divide both sides by -6, the multiplier of y, and you get:
\n" ); document.write( ".
\n" ); document.write( " $\"y+=+%28-4%2F-6%29x+-+30%2F-6+=+%282%2F3%29x+%2B+5\"$
\n" ); document.write( ".
\n" ); document.write( "Now replace the y with f(x) and you get:
\n" ); document.write( ".
\n" ); document.write( " $\"f%28x%29+=+%282%2F3%29x+%2B+5\"$
\n" ); document.write( ".
\n" ); document.write( "Hope this helps. \n" ); document.write( "
