Algebra.Com's Answer #62215 by bucky(2189)![]() ![]() ![]() You can put this solution on YOUR website! Given the equation: \n" ); document.write( ". \n" ); document.write( " \n" ); document.write( ". \n" ); document.write( "Your first step results in: \n" ); document.write( ". \n" ); document.write( " \n" ); document.write( ". \n" ); document.write( "You have made a mistake in the distributive multiplication on the left side. You must multiply \n" ); document.write( "the 2 times both quantities in the parentheses. You only multiplied the 2 times the 2x and \n" ); document.write( "you forgot to multiply it times the -2 also. If you had done that you would have gotten: \n" ); document.write( ". \n" ); document.write( " \n" ); document.write( ". \n" ); document.write( "Subtracting x from both sides you would then get: \n" ); document.write( ". \n" ); document.write( " \n" ); document.write( ". \n" ); document.write( "and then adding 4 to both sides would result in: \n" ); document.write( ". \n" ); document.write( " \n" ); document.write( ". \n" ); document.write( "Hope this helps you to understand the problem and where the mistake was made. \n" ); document.write( " |
