Algebra.Com's Answer #8401 by lainey(7) You can put this solution on YOUR website! 2(x+4)=3x\r \n" ); document.write( "\n" ); document.write( "You would have to apply the distributive property to this problem. \n" ); document.write( "1.) 2*x= 2x \n" ); document.write( "2.) 2*4= 8 \n" ); document.write( "3.) Since x is unknown we can not change anything involving the variable. So your solution would be 2x + 8 = 3x\r \n" ); document.write( "\n" ); document.write( " \n" ); document.write( "The above method written by Lainey is right for the most part, though it does not arrive at the right conclusion (In other words, step 3 is wrong). We foil out everything first to get 2x+8=3x. Now we can isolate the variable. \n" ); document.write( " \n" ); document.write( "2x+8=3x (subtract 2x from each side) \n" ); document.write( "8=x \n" ); document.write( " \n" ); document.write( "With that we know that x=8, and so you're solution would not be 2x+8=3x, but 8, as we have successfully solved for x. \n" ); document.write( " |
