Algebra.Com's Answer #160417 by Alan3354(69443)![]() ![]() You can put this solution on YOUR website! x-5 over x+4 = x-1 over x+3 Solve for x \n" ); document.write( "Cross multiply \n" ); document.write( "(x-5)*(x+3) = (x+4)*(x-1) \n" ); document.write( " \n" ); document.write( "-2x-15 = 3x-4 \n" ); document.write( "5x = -11 \n" ); document.write( "x = -11/5 \n" ); document.write( "----------------- \n" ); document.write( "7 over x-2 + 2 over x+2 = -4x over x^2-4 solve for x \n" ); document.write( " \n" ); document.write( "(x^2-4) = ((x-2)*(x+2) and is the common denominator \n" ); document.write( "Multiply thru by (x^2-4) \n" ); document.write( "7(x+2) + 2(x-2) = -4x \n" ); document.write( "7x+14 + 2x-4 = -4x \n" ); document.write( "9x + 10 = -4x \n" ); document.write( "13x = -10 \n" ); document.write( "x = -10/13 \n" ); document.write( " \n" ); document.write( " |
