Algebra.Com's Answer #75733 by Earlsdon(6294)![]() ![]() ![]() You can put this solution on YOUR website! Let x and y be the two numbers. \n" ); document.write( "x+y = 32 \n" ); document.write( "x-y = 10 Rewrite this as x = y+10 and substitute for x in the first equation. \n" ); document.write( "(y+10) + y = 32 Simplify and solve for y. \n" ); document.write( "2y+10 = 32 Subtract 10 from both sides. \n" ); document.write( "2y = 22 Divide both sides by 2. \n" ); document.write( "y = 11 \n" ); document.write( "x = y+10 \n" ); document.write( "x = 11+10 \n" ); document.write( "x = 21\r \n" ); document.write( "\n" ); document.write( "The two numbers are: 21 and 11 \n" ); document.write( " |
