Algebra.Com's Answer #620851 by fractalier(6550)![]() ![]() You can put this solution on YOUR website! Okay, if two quantities are both equal to y, as in \n" ); document.write( "y=x+15 and \n" ); document.write( "y=2x \n" ); document.write( "then you can set them equal to each other...we can write \n" ); document.write( "x + 15 = 2x \n" ); document.write( "Now subtract x from both sides and get \n" ); document.write( "x = 15 \n" ); document.write( "Then since y = 2x, \n" ); document.write( "y = 30 \n" ); document.write( " |
