Algebra.Com's Answer #618363 by addingup(3677)![]() ![]() You can put this solution on YOUR website! Let's call the 5 x and the 20 z: \n" ); document.write( "x+z= 28. If we subtract z from both sides we get: \n" ); document.write( "x= 28-z Let's use this value for x in the next equation: \n" ); document.write( "--------------------------------------------- \n" ); document.write( "5(28-z)+20z= 350 \n" ); document.write( "140-5z+20z= 350 Subtract 140 on both sides and add on left: \n" ); document.write( "15z= 210 \n" ); document.write( "z= 210/15 \n" ); document.write( "z= 14 he has 14 $5 bills \n" ); document.write( "And how many $20 bills+ 28-14 \n" ); document.write( "J \n" ); document.write( " \n" ); document.write( " |
