Algebra.Com's Answer #23758 by fractalier(6550)![]() ![]() You can put this solution on YOUR website! Let's call our two numbers x and y. From the facts in the problem, we have \n" ); document.write( "x - y = 45 and \n" ); document.write( "y = 3x - 3 \n" ); document.write( "Substituting this into the first equation we have \n" ); document.write( "x - (3x - 3) = 45 \n" ); document.write( "-2x + 3 = 45 \n" ); document.write( "-2x = 42 \n" ); document.write( "x = -21 \n" ); document.write( "Then we can find y by \n" ); document.write( "y = 3(-21) - 3 \n" ); document.write( "y = -66 \n" ); document.write( " |
