Algebra.Com's Answer #633947 by fractalier(6550) You can put this solution on YOUR website! Okay, from \n" ); document.write( "log(5x+2)-log(x-1)=0.7782 \n" ); document.write( "combine logs first and get \n" ); document.write( "log((5x+2)/(x-1)) = .7782 \n" ); document.write( "Now exponentiate 10-to-the and get \n" ); document.write( "(5x+2)/(x-1) = 10^.7782 \n" ); document.write( "(5x+2)/(x-1) = 6 \n" ); document.write( "Now cross-multiply \n" ); document.write( "5x + 2 = 6x - 6 \n" ); document.write( "and solve, giving us \n" ); document.write( "x = 8 \n" ); document.write( " |
