Algebra.Com's Answer #16570 by jb007mi6(53) ![]() You can put this solution on YOUR website! it helps to label your equations. lets say (3x+y=5 is \"1\" and the other is \"2\"\r \n" ); document.write( "\n" ); document.write( "solve each equation for y\r \n" ); document.write( "\n" ); document.write( "\"1\" ----- y=-3x+5 \n" ); document.write( "\"2\" ----- y=2x-10\r \n" ); document.write( "\n" ); document.write( "since both equations both equal \"y\" you can set them equal to eachother\r \n" ); document.write( "\n" ); document.write( "-3x+5=2x-10 \n" ); document.write( "solve this equation for \"X\" \n" ); document.write( "-5x=-15 \n" ); document.write( "x=3\r \n" ); document.write( "\n" ); document.write( "put the value of \"3\" into the first (or second) equation \r \n" ); document.write( "\n" ); document.write( "in \"1\" 3(3)+y=5 \n" ); document.write( "9+y=5 \n" ); document.write( "y=-4 \n" ); document.write( "check your answers in the other equation as well \n" ); document.write( " |
