eggs: x
\n" ); document.write( "bread: y
\n" ); document.write( "---------------------------------------------------------
\n" ); document.write( "3x+5y= 6.90 Multiply both sides times 2
\n" ); document.write( "4x+2y= 5.70 Multiply both sides times 5 and subtract from above:
\n" ); document.write( "-----------------------------------------
\n" ); document.write( "6x+10y= 13.80
\n" ); document.write( "-
\n" ); document.write( "20x+10y= 28.50
\n" ); document.write( "----------------
\n" ); document.write( "-14x = -14.70 divide both sides by -14
\n" ); document.write( "x = 1.05 And now let's find y:
\n" ); document.write( "3(1.05)+5y= 6.90
\n" ); document.write( "3.15+5y= 6.90 subtract 3.15 from both sides
\n" ); document.write( "5y= 3.75 divide both sides by 5
\n" ); document.write( "y= 0.75
\n" ); document.write( "-----------------------------------------------------
\n" ); document.write( "Check:
\n" ); document.write( "3x+5y= 6.90; 3(1.05)+5(0.75)= 6.90. We have the correct answer.
\n" ); document.write( "Now let's see if we can prove the other equation to be true as well:
\n" ); document.write( "4x+2y= 5.70; 4(1.05)+2(0.75)= 5.70. Again we have the correct answer.
\n" ); document.write( "A dozen eggs is $1.05 and a loaf of bread $0.75
\n" ); document.write( "
\n" ); document.write( "
\n" );
