Algebra.Com's Answer #481654 by ankor@dixie-net.com(22740) You can put this solution on YOUR website! Assuming the problem is \n" ); document.write( " \n" ); document.write( "Solve for x \n" ); document.write( "multiply both sides by x \n" ); document.write( "x + 16 = 8x \n" ); document.write( "Subtract x from both sides \n" ); document.write( "16 = 8x - x \n" ); document.write( "16 = 7x \n" ); document.write( "divide both sides by 7 \n" ); document.write( "x = \n" ); document.write( ": \n" ); document.write( "However if the problem is \n" ); document.write( "x + \n" ); document.write( "multiply both sides by x and you have \n" ); document.write( "x^2 + 16 = 8x \n" ); document.write( "Arrange as a quadratic equation \n" ); document.write( "x^2 - 8x = 16 = 0 \n" ); document.write( "factors to \n" ); document.write( "(x-4)(x-4) = 0 \n" ); document.write( "x = 4 \n" ); document.write( ": \n" ); document.write( ": \n" ); document.write( "The abundant use of brackets is very helpful in defining these problems.
