Equation 1: $\"A+%2B+7+=+B\"$
\n" ); document.write( "Equation 2: $\"2B+-+26+=+3A\"$
\n" ); document.write( "Plug (A + 7) into equation 2 for B
\n" ); document.write( "Equation 2: $\"2B+-+26+=+3A\"$
\n" ); document.write( " $\"2%2A%28A+%2B+7%29+-+26+=+3A\"$
\n" ); document.write( "Simplify
\n" ); document.write( " $\"2A+%2B+14+-+26+=+3A\"$
\n" ); document.write( "Combine like terms
\n" ); document.write( " $\"2A+-12+=+3A\"$
\n" ); document.write( "Subtract 2A from both sides
\n" ); document.write( " $\"highlight%28-12+=+A%29\"$
\n" ); document.write( "Plug -12 into equation 1 for A
\n" ); document.write( "Equation 1: $\"A+%2B+7+=+B\"$
\n" ); document.write( " $\"%28-12%29+%2B+7+=+B\"$
\n" ); document.write( " $\"highlight_green%28-5+=+B%29\"$ \n" ); document.write( "
