Algebra.Com's Answer #39673 by rcmcc(152)![]() ![]() You can put this solution on YOUR website! 7x – 5 + 3x = 6 + x – 10 \n" ); document.write( "is -4 the solution... No.\r \n" ); document.write( "\n" ); document.write( "when you substitute in -4 for x you recieve the answer -35=-8, they are unequal.\r \n" ); document.write( "\n" ); document.write( "7x – 5 + 3x = 6 + x – 10 \n" ); document.write( "first you can combine like terms\r \n" ); document.write( "\n" ); document.write( "10x-5=x-4\r \n" ); document.write( "\n" ); document.write( "remove the x from the right hand side and you get \n" ); document.write( "9X-5=-4\r \n" ); document.write( "\n" ); document.write( "remove the -5 from the right hand side \n" ); document.write( "you get the equation \n" ); document.write( "9x=1 \n" ); document.write( "divide by 9 \n" ); document.write( "x=(1/9) \n" ); document.write( "when you substitute in to the equation (1/9) for x you get the statement\r \n" ); document.write( "\n" ); document.write( "-3.8888=-3.8888 \n" ); document.write( " |
