Algebra.Com's Answer #151624 by algebrapro18(249)![]() ![]() ![]() You can put this solution on YOUR website! This is a proportion and to solve proportions you just cross multiply. Doing so we get: \r \n" ); document.write( "\n" ); document.write( "x+3/x-1 = x+2/x-3 \n" ); document.write( "(x+3)(x-3) = (x-1)(x+2) \r \n" ); document.write( "\n" ); document.write( "Now we F.O.I.L. these out and solve. \r \n" ); document.write( "\n" ); document.write( "(x+3)(x-3) = (x-1)(x+2) \n" ); document.write( "x^2 - 9 = x^2 + x - 2 \n" ); document.write( "0 = x^2 - x^2 + x -2 + 9 \n" ); document.write( "0 = x + 7 \n" ); document.write( "x = -7 \r \n" ); document.write( "\n" ); document.write( "Plugging in we see that this is the solution. \n" ); document.write( " |
