Algebra.Com's Answer #91023 by bucky(2189)![]() ![]() ![]() You can put this solution on YOUR website! Given: \n" ); document.write( ". \n" ); document.write( " \n" ); document.write( ". \n" ); document.write( "When you multiply both sides by 3 you get: \n" ); document.write( ". \n" ); document.write( " \n" ); document.write( ". \n" ); document.write( "On the left side the 3 in the numerator cancels with the 3 in the denominator to give: \n" ); document.write( ". \n" ); document.write( " \n" ); document.write( ". \n" ); document.write( "On the left side you are left with just -x and on the right side the 3 times the 3 is 9. \n" ); document.write( "This makes the equation: \n" ); document.write( ". \n" ); document.write( " \n" ); document.write( ". \n" ); document.write( "But you want to solve for +x, so just multiply both sides by -1 and you have: \n" ); document.write( ". \n" ); document.write( " \n" ); document.write( ". \n" ); document.write( "Check the answer by returning to the original equation you were given and substitute into \n" ); document.write( "that equation -9 for x. So start with: \n" ); document.write( ". \n" ); document.write( " \n" ); document.write( ". \n" ); document.write( "When you replace x with -9 it becomes: \n" ); document.write( ". \n" ); document.write( " \n" ); document.write( ". \n" ); document.write( "The two minus signs in the numerator on the right side combine to be a + sign and the \n" ); document.write( "equation is then: \n" ); document.write( ". \n" ); document.write( " \n" ); document.write( ". \n" ); document.write( "And when you divide out the left side the result is: \n" ); document.write( ". \n" ); document.write( " \n" ); document.write( ". \n" ); document.write( "which is true. Therefore, x = -9 is the correct answer. \n" ); document.write( ". \n" ); document.write( "Hope this helps you to find your mistake. \n" ); document.write( ". \n" ); document.write( " \n" ); document.write( " |
