Algebra.Com's Answer #175313 by stanbon(75887) ![]() You can put this solution on YOUR website! How do I set this up? The larger of two numbers is 1 more than twice the smaller. Three times the larger exceeds 5 times the smaller by 10. Find the numbers. \n" ); document.write( "--------------- \n" ); document.write( "Let \"x\" be the larger. \n" ); document.write( "Let \"y\" be the smaller. \n" ); document.write( "------------------------- \n" ); document.write( "Equations: \n" ); document.write( "x = 2y+1 \n" ); document.write( "2x -5y = 10 \n" ); document.write( "--------------------- \n" ); document.write( "Substitute x = 2y+1 into the 2nd equation and solve for \"y\": \n" ); document.write( "2(2y+1) - 5y = 10 \n" ); document.write( "-y = 8 \n" ); document.write( "y = -8 \n" ); document.write( "--------------- \n" ); document.write( "Substitute y =-8 into x = 2y+1 to solve for \"x\": \n" ); document.write( "x = 2*-8+1 = -15 \n" ); document.write( "======================== \n" ); document.write( "Cheers, \n" ); document.write( "Stan H. \n" ); document.write( " |
