Algebra.Com's Answer #403 by usyim88hk(158)![]() ![]() ![]() You can put this solution on YOUR website! OK, first we have to takes out both x and 3x from both equations, so lets multiply equation 1 by -3 so then we can takes the x-terms away from both equations: \n" ); document.write( ": \n" ); document.write( "(equation 1) \n" ); document.write( "(-3)(x-2y) = 0(-3) \n" ); document.write( "-3x+6y = 0 \n" ); document.write( ": \n" ); document.write( "So now we can use substituion now \n" ); document.write( "-3x+6y = 0 \n" ); document.write( "3x+y = 0 \n" ); document.write( "----------- \n" ); document.write( "7y = 0 \n" ); document.write( "y = 0 \n" ); document.write( "-------------- \n" ); document.write( "So y is equal to zero \n" ); document.write( " |
