(15/x) + (9x-7)/(x+2) =9 \n" ); document.write( "------------ \n" ); document.write( "Multiply thru by x(x+2) to get: \n" ); document.write( "15(x+2) + (9x-7)x = 9x(x+2) \n" ); document.write( "Expand and then simplify: \n" ); document.write( "15x + 30 + 9x^2 -7x = 9x^2+18x \n" ); document.write( "8x + 30 = 18x \n" ); document.write( "Solve for \"x\": \n" ); document.write( "10x = 30 \n" ); document.write( "x = 3 \n" ); document.write( "================== \n" ); document.write( "Checking the answer: \n" ); document.write( "(15/3) + (27-7)/5 = 9 \n" ); document.write( "5 + 4 = 9 \n" ); document.write( "==================== \n" ); document.write( "Cheers, \n" ); document.write( "Stan H. \n" ); document.write( " |
