Algebra.Com's Answer #14676 by elima(1433)![]() ![]() ![]() You can put this solution on YOUR website! First lets take the second equation and solve for x; \n" ); document.write( "x-3y=-4 \n" ); document.write( "x=-4+3y \n" ); document.write( "Now substitute that for x in equation 1; \n" ); document.write( "(-4+3y)+2y=6 \n" ); document.write( "-4+5y=6 \n" ); document.write( "5y=6+4 \n" ); document.write( "5y=10 \n" ); document.write( "y=2 \n" ); document.write( "Now we have what y =, lets plug that into the equation and solve for x; \n" ); document.write( "x-3(2)=-4 \n" ); document.write( "x-6=-4 \n" ); document.write( "x=-4+6 \n" ); document.write( "x=2 \n" ); document.write( "Hope you understand \n" ); document.write( "=) \n" ); document.write( " |
