Paul had 30 more marbles probably? or less?
\n" ); document.write( "If more so, then
\n" ); document.write( "Paul has x+30
\n" ); document.write( "Peter has x
\n" ); document.write( "Peter gave 15 marbles: -->x-15 so Paul had x+45 marbles now
\n" ); document.write( "Equation:
\n" ); document.write( "2(x-15)=x+45\r
\n" ); document.write( "\n" ); document.write( "2x-30=x+45
\n" ); document.write( "x=75
\n" ); document.write( "75+30=105
\n" ); document.write( "Hence, Peter has 75 marbles and Paul has 105 marbles.
