Assume, area of Lake Winnipeg is x km^2 and area of Lake Brandon is y km^2\r
\n" ); document.write( "\n" ); document.write( "Their combined area is 29800 km^2
\n" ); document.write( "x + y = 29800\r
\n" ); document.write( "\n" ); document.write( "Area of lake brandon is 700 km^2 less than a quarter of area of lake winnipeg
\n" ); document.write( "x/4 - 700 = y
\n" ); document.write( "x - 2800 = 4y
\n" ); document.write( "x - 4y = 2800
\n" ); document.write( "-x + 4y = -2800\r
\n" ); document.write( "\n" ); document.write( "Solving the 2 equations now
\n" ); document.write( "x + y = 29800
\n" ); document.write( "-x + 4y = -2800
\n" ); document.write( "-----------------
\n" ); document.write( "5y = 27000
\n" ); document.write( "-----------------\r
\n" ); document.write( "\n" ); document.write( "So y = 27000/5 = 5400
\n" ); document.write( "And x= 29800 - 5400 = 24400\r
\n" ); document.write( "\n" ); document.write( "So area of lake winnipeg is 24400 km^2 and area of lake brandon is 5400 km^2\r
\n" ); document.write( "
\n" ); document.write( "
