Equation 1: $\"B+=+A+%2B+4\"$
\n" ); document.write( "Equation 2: $\"3B+%2B+4A+=+61\"$
\n" ); document.write( "--------------------------
\n" ); document.write( "Plug (A+4) into equation 2 for B.
\n" ); document.write( "Equation 2: $\"3B+%2B+4A+=+61\"$
\n" ); document.write( " $\"3%2A%28A%2B4%29+%2B+4A+=+61\"$
\n" ); document.write( "Multiply the 3 through.
\n" ); document.write( " $\"3A+%2B+12+%2B+4A+=+61\"$
\n" ); document.write( "Combine like terms.
\n" ); document.write( " $\"7A+%2B+12+=+61\"$
\n" ); document.write( "Subtract 12 from both sides.
\n" ); document.write( " $\"7A+=+49%29\"$
\n" ); document.write( "Divide both sides by 7.
\n" ); document.write( " $\"highlight%28A+=+7%29\"$
\n" ); document.write( "-----------------------
\n" ); document.write( "Plug 7 into equation 1 for A.
\n" ); document.write( "Equation 1: $\"B+=+A+%2B+4\"$
\n" ); document.write( " $\"B+=+%287%29+%2B+4\"$
\n" ); document.write( " $\"highlight_green%28B+=+11%29\"$ \n" ); document.write( "
