\"2x%2B3y=6\"
\n" ); document.write( "\"x=+-1\"
\n" ); document.write( ".
\n" ); document.write( "Two variables are involved in this set of two equations ... x and y. But the problem
\n" ); document.write( "already tells you that x is equal to -1. With this information you can solve for y by
\n" ); document.write( "substitution. Just substitute -1 for x in the top equation. When you do the top equation
\n" ); document.write( "becomes:
\n" ); document.write( ".
\n" ); document.write( "\"2%2A%28-1%29+%2B+3%2Ay+=+6\"
\n" ); document.write( ".
\n" ); document.write( "This simplifies to:
\n" ); document.write( ".
\n" ); document.write( "\"-2+%2B+3%2Ay+=+6\"
\n" ); document.write( ".
\n" ); document.write( "Eliminate the -2 on the left side by adding +2 to both sides to get:
\n" ); document.write( ".
\n" ); document.write( "\"3%2Ay+=+8\"
\n" ); document.write( ".
\n" ); document.write( "Solve for y by dividing both sides by 3. This results in:
\n" ); document.write( ".
\n" ); document.write( "\"y+=+8%2F3\"
\n" ); document.write( ".
\n" ); document.write( "The decimal equivalent of this is:
\n" ); document.write( ".
\n" ); document.write( "\"y+=+2.66666+...\"
\n" ); document.write( ".
\n" ); document.write( "Hope this helps you to understand a way of solving the equation.
