You can put this solution on YOUR website!
You can make the table, but here is how I
\n" ); document.write( "would solve it:
\n" ); document.write( "How many times Lisa's age is Marcus now?
\n" ); document.write( " $\"+49%2F15+=+3.27+\"$
\n" ); document.write( "Let $\"x\"$ = number of years I want to add to both ages
\n" ); document.write( "so that $\"+49+%2B+x+=+3%2A%28+15+%2B+x+%29+\"$
\n" ); document.write( " $\"+49+%2B+x+=+45+%2B+3x+\"$
\n" ); document.write( " $\"+2x+=+49+-+45+\"$
\n" ); document.write( " $\"+2x+=+4+\"$
\n" ); document.write( " $\"+x+=+2+\"$
\n" ); document.write( "In 2 years, Marcus will be 3 times Lisa's age
\n" ); document.write( "check:
\n" ); document.write( " $\"+49+%2B+2+=+51+\"$
\n" ); document.write( " $\"+15+%2B+2+=+17+\"$
\n" ); document.write( " $\"+51%2F17+=+3+\"$
\n" ); document.write( "OK
\n" ); document.write( "For a table, you can list x, 49 + x, 15 + x, 3*(15 + x)
\n" ); document.write( "and x=1, x=2, x=3 \n" ); document.write( "

\n" );
