x+2y=0,2x-6y=5 solve each system by the addition method. Thanks!!\r

\n" ); document.write( "\n" ); document.write( "The addition method of solving a system of equations is also known as the elimination method, where one variable is eliminated in order to determine the value of the other.\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "x + 2y = 0 ----- eq (i)
\n" ); document.write( "2x - 6y = 5 ------ eq (ii)
\n" ); document.write( "- 2x - 4y = 0 ------ Multiplying eq (i) by - 2 ------ eq (iii)\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "- 10y = 5 ------ Adding eqs (ii) & (iii)\r
