Algebra.Com's Answer #647972 by addingup(3677)![]() ![]() You can put this solution on YOUR website! Let x be the number. \n" ); document.write( "x/1+1/x = 5/2 Here, x/1=x, so let's simplify: \n" ); document.write( "x+1/x = 5/2 \n" ); document.write( "Multiply all terms times 2x: \n" ); document.write( "2x^2+2 = 5x \n" ); document.write( "Subtract 5x from both sides: \n" ); document.write( "2x^2-5x+2 = 0 \n" ); document.write( "Factor the equation using FOIL: \n" ); document.write( "(x-2)(2x-1)= 0 \n" ); document.write( "Split into 2 equations and solve for each: \n" ); document.write( "x-2 = 0 or 2x-1 = 0 \n" ); document.write( "x = 2 or x = 1/2 \n" ); document.write( "Let's try the two possibilities to see which one is the correct answer: \n" ); document.write( "2+1/2 = 4/2+1/2 = 5/2 \n" ); document.write( "Great, right off the bat I found the answer. Discard the other equation. \n" ); document.write( "John\r \n" ); document.write( "\n" ); document.write( " \n" ); document.write( " |
