You can put this solution on YOUR website!
Equation 1: \"A+%2B+B+=+84\"
\n" ); document.write( "Equation 2: \"A+-+B+=+30\"
\n" ); document.write( "Solve equation 2 for A
\n" ); document.write( "\"A+=+B+%2B+30\"
\n" ); document.write( "Now plug (B + 30) into equation 1 for A
\n" ); document.write( "Equation 1: \"A+%2B+B+=+84\"
\n" ); document.write( "\"%28B+%2B+30%29+%2B+B+=+84\"
\n" ); document.write( "Combine like terms
\n" ); document.write( "\"2B+%2B+30+=+84\"
\n" ); document.write( "Subtract 30 from both sides
\n" ); document.write( "\"2B+=+54\"
\n" ); document.write( "Divide both sides by 2
\n" ); document.write( "\"highlight%28B+=+27%29\"
\n" ); document.write( "Now plug 27 into equation 2 for B
\n" ); document.write( "\"A+=+B+%2B+30\"
\n" ); document.write( "\"A+=+%2827%29+%2B+30\"
\n" ); document.write( "\"highlight_green%28A+=+57%29\"
\n" ); document.write( "
\n" );
