To solve for Y, we have to get Y by itself on one side of our equal sign. So, for 3x + 4y + 12 = 0, first we can subtract 12 from both sides of our equal sign:
\n" ); document.write( "3x + 4y + 12 - 12 = 0 - 12, giving us\r
\n" ); document.write( "\n" ); document.write( "3x + 4y = -12\r
\n" ); document.write( "\n" ); document.write( "Next, we can subtract 3x from both sides of our equal sign: 3x - 3x + 4y = -12 - 3x, giving us\r
\n" ); document.write( "\n" ); document.write( "4y = -12 - 3x\r
\n" ); document.write( "\n" ); document.write( "Finally, we can get the y by itself by dividing both sides by 4:\r
\n" ); document.write( "\n" ); document.write( "\"4y%2F4+=+%28-12+-+3x%29%2F4\"\r
\n" ); document.write( "\n" ); document.write( "This leaves us with\r
\n" ); document.write( "\n" ); document.write( "\"y+=+%28-12+-+3x%29%2F4\"\r
\n" ); document.write( "\n" ); document.write( "The right side of our equal sign can be simplified, because we know that\r
\n" ); document.write( "\n" ); document.write( "\"%28-12+-+3x%29%2F4\" is the same thing as \"-%2812%2F4%29+-+3x%2F4\"\r
\n" ); document.write( "\n" ); document.write( "Reducing this down results in our final answer\r
\n" ); document.write( "\n" ); document.write( "Final Answer: \"y+=+-3+-+3x%2F4\"
\n" ); document.write( "
\n" );
