Algebra.Com's Answer #835054 by Theo(13342) You can put this solution on YOUR website! x = what donna paid. \n" ); document.write( "y = what pat paid. \n" ); document.write( "x + y = 450 \n" ); document.write( "x = y + 110 \n" ); document.write( "replace x with y + 110 to get: \n" ); document.write( "y + 110 + y = 450 \n" ); document.write( "combine like terms to get 2y + 110 = 450 \n" ); document.write( "subtract 110 from both sides of the equation to get 2y = 340 \n" ); document.write( "solve for y to get y = 170 \n" ); document.write( "x = 170 + 110 = 280 \n" ); document.write( "280 + 170 = 450. \n" ); document.write( "solution is confirmed to be good. \n" ); document.write( "solution is donna paid 280 and pat paid 170. \n" ); document.write( "here is the solution graphically. \n" ); document.write( " \n" );
