Algebra.Com's Answer #499196 by kmadison(20) You can put this solution on YOUR website! Solve for x over the real numbers: \n" ); document.write( " \n" ); document.write( "Move everything to the left hand side. \n" ); document.write( "Subtract log(5)+log(x-2) from both sides: \n" ); document.write( " \n" ); document.write( "Combine logarithms. \n" ); document.write( " \n" ); document.write( "Eliminate the logarithm from the left hand side. \n" ); document.write( "Cancel logarithms by taking exp of both sides: \n" ); document.write( " \n" ); document.write( "Multiply both sides by a polynomial to clear fractions. \n" ); document.write( "Multiply both sides by 5 (x-2): \n" ); document.write( " \n" ); document.write( "Write the linear polynomial on the right hand side in standard form. \n" ); document.write( "Expand out terms of the right hand side: \n" ); document.write( " \n" ); document.write( "Isolate x to the left hand side. \n" ); document.write( "Subtract 5 x from both sides: \n" ); document.write( " \n" ); document.write( "Solve for x. \n" ); document.write( "Divide both sides by -2: \n" ); document.write( "Answer: |
