Algebra.Com's Answer #300570 by stanbon(75887)![]() ![]() ![]() You can put this solution on YOUR website! 1. One number is five times the other number. If the two numbers total 26, find the numbers. \n" ); document.write( "x = 5y \n" ); document.write( "x+y = 26 \n" ); document.write( "---- \n" ); document.write( "Substitute for \"x\" and solve for \"y\": \n" ); document.write( "5y+y = 26 \n" ); document.write( "6y = 26 \n" ); document.write( "y = 13/3 = 4 1/3 \n" ); document.write( "---- \n" ); document.write( "Solve for \"x\": \n" ); document.write( "x = 5y \n" ); document.write( "x = 5(13/3) = 65/3 = 21 2/3 \n" ); document.write( "=============================== \n" ); document.write( " \n" ); document.write( "2.
