Algebra.Com's Answer #365383 by TutorDelphia(193)![]() ![]() You can put this solution on YOUR website! Since the first equation is already solved for y we can use substitution replacing y with 4x+6 \n" ); document.write( "2(4x+6)=-8x-8 \n" ); document.write( "Distribute the 2 \n" ); document.write( "8x+12=-8x-8 \n" ); document.write( "Add 8x to both sides \n" ); document.write( "16x+12=-8 \n" ); document.write( "subtract 12 from both sides \n" ); document.write( "16x=-20 \n" ); document.write( "divide both sides by 16 \n" ); document.write( "x=-20/16 \n" ); document.write( "Simplify the fraction \n" ); document.write( "x=-5/4 \n" ); document.write( "Sub it -5/4 for x \n" ); document.write( "y=4*(-5/4)+6 \n" ); document.write( "y=1\r \n" ); document.write( "\n" ); document.write( " \n" ); document.write( " |
