Algebra.Com's Answer #310499 by confusedgirl81(14)![]() ![]() You can put this solution on YOUR website! 3x+5(8-x) = 24-x distribute 5 first \n" ); document.write( "3x+40-5x = 24-x \n" ); document.write( "-2x+40 = 24-x subtract 40 from both sides \n" ); document.write( "-2x = 24-40-x now add x to both sides \n" ); document.write( "-2x+x = 24-40 solve both sides, remember x is the same as 1x \n" ); document.write( "-1x = -16 divide both sides by -1 \n" ); document.write( "x = 16\r \n" ); document.write( "\n" ); document.write( "when in doubt always check your answer \n" ); document.write( "3x+5(8-x) = 24-x now substitute 16 for x \n" ); document.write( "3(16)+5(8-16) = 24-16 \n" ); document.write( "48+5(-8) = 8 \n" ); document.write( "48-40 = 8 \n" ); document.write( "8 = 8 \r \n" ); document.write( "\n" ); document.write( "so your answer is x = 16 \n" ); document.write( " \n" ); document.write( " |
