Simon has $85.
\n" ); document.write( "Joe has $70.
\n" ); document.write( "Joe spends more than $5 than Simon, but we do not know how much they spent, so we will express it as \"x\".
\n" ); document.write( "At the end, Simon has twice as much money as left as Joe, so we will know the solution will be S = 2J, assuming that S = Simon and J = Joe.
\n" ); document.write( "Based on the statement above, we can assume that.
\n" ); document.write( "\"+S+=+85+-+x+\"
\n" ); document.write( "\"+J+=+70+-+%28x+%2B+5%29+\"
\n" ); document.write( "As with the equation above, we can plug in S and J with the equation of S = 2J
\n" ); document.write( "\"+85+-+x+=+2%2870+-+%28x+%2B+5%29%29+\"
\n" ); document.write( "\"+85+-+x+=+2%2870+-+x+-+5%29+\" Distribution
\n" ); document.write( "\"+85+-+x+=+140+-+2x+-+10%29+\" Distribution
\n" ); document.write( "\"+85+-+x+=+130+-+2x+\" Combine Like Terms
\n" ); document.write( "\"+85+-+85+-+x+=+130+-+85+-+2x+\" Subtraction Property of Equality
\n" ); document.write( "\"+-x+%2B+2x+=+45+-+2x+%2B+2x+\" Addition Property of Equality
\n" ); document.write( "\"+x+=+45+\" Simplify\r
\n" ); document.write( "\n" ); document.write( "Now we will plug in x for the S and J.
\n" ); document.write( "\"+S+=+85+-+x+\"
\n" ); document.write( "\"+S+=+85+-+45+\" Substitution
\n" ); document.write( "\"+S+=+40+\" Simplify\r
\n" ); document.write( "\n" ); document.write( "\"J+=+70+-+%28x+%2B+5%29+\"
\n" ); document.write( "\"+J+=+70+-+%2845+%2B+5%29+\" Substitution
\n" ); document.write( "\"+J+=+70+-+50+\" Combine Like Terms
\n" ); document.write( "\"+J+=+20+\" Simplify
\n" ); document.write( "Now, we will plug in S and J for the S = 2J equation to verify if it is true.
\n" ); document.write( "\"+S+=+2J+\"
\n" ); document.write( "\"+40+=+2%2820%29+\" Substitution
\n" ); document.write( "\"+40+=+40+\"\r
\n" ); document.write( "\n" ); document.write( "Simon has $40 and Joe has $20.
\n" ); document.write( "
\n" );
