Algebra.Com's Answer #274043 by rfer(16322) ![]() You can put this solution on YOUR website! you have done the hard part except you lost the y with the first 5 \n" ); document.write( "180-30y+5y=5 \n" ); document.write( "-25y=-175 \n" ); document.write( "y=7 \n" ); document.write( "now plug in the 7 \n" ); document.write( "solve for x \n" ); document.write( "6x+5*7=5 \n" ); document.write( "6x+35=5 \n" ); document.write( "6x=-30 \n" ); document.write( "x=-5 \n" ); document.write( "------------------- \n" ); document.write( "-5=30-5*7 \n" ); document.write( " |
