Algebra.Com's Answer #509201 by pmesler(52) You can put this solution on YOUR website! In this problem it looks like they want you to solve for c. \r \n" ); document.write( "\n" ); document.write( "68 + 2c = 180.\r \n" ); document.write( "\n" ); document.write( "First we need to simplify and isolate the c term on the left side. We do this by subtracting 68 from both sides. \r \n" ); document.write( "\n" ); document.write( "68 (-68) + 2c = 180 (-68) \r \n" ); document.write( "\n" ); document.write( "0 + 2c = 112\r \n" ); document.write( "\n" ); document.write( "2c = 112\r \n" ); document.write( "\n" ); document.write( "Now to solve for c we simply divide each side by 2 \r \n" ); document.write( "\n" ); document.write( "2c/2 = 112/2\r \n" ); document.write( "\n" ); document.write( "The 2's divide out and we are left with \r \n" ); document.write( "\n" ); document.write( "c = 56. \r \n" ); document.write( "\n" ); document.write( "Now, let's check our solutions by plugging it back into the original equation.\r \n" ); document.write( " \n" ); document.write( "\n" ); document.write( "68 + 2(56) = 180\r \n" ); document.write( "\n" ); document.write( "68 + 112 = 180\r \n" ); document.write( "\n" ); document.write( "180 = 180. It checks out so c = 56 is the correct answer. \n" ); document.write( " |
