Algebra.Com's Answer #99472 by AlexxsDad(4)![]() ![]() ![]() You can put this solution on YOUR website! Your two equations are the same: -x+4 is the exact same thing as -1x+4. The \"1\" is usually omitted; x is the same as 1x (because there's only one), and -x is the same as -1x. So we have:\r \n" ); document.write( "\n" ); document.write( "-9x+6=-x+4\r \n" ); document.write( "\n" ); document.write( "Strategy: put x's on one side and number on the other\r \n" ); document.write( "\n" ); document.write( "6-4 = 9x-x (study that move) \n" ); document.write( "2 = 8x\r \n" ); document.write( "\n" ); document.write( "or if you prefer:\r \n" ); document.write( "\n" ); document.write( "8x = 2 (they're equal; it doesn't matter what side of the equal sign they're on)\r \n" ); document.write( "\n" ); document.write( "divide both sides by 8 so your x is identified:\r \n" ); document.write( "\n" ); document.write( "x = 2/8, better known as x = 1/4 \n" ); document.write( " |
