Algebra.Com's Answer #37979 by Lacey020991(49)![]() ![]() ![]() You can put this solution on YOUR website! Where the y is on the first equation, your going to the second equation in and solve. \n" ); document.write( ". \n" ); document.write( "2x + 2(4x+0) = 0 ~~~~~Distribute the 2 \n" ); document.write( "2x + 8x + 0 = 0 ~~~~~~Combine like terms \n" ); document.write( "10x = 0 ~~~~~~~~~~~~~~Divide both sides by 10 \n" ); document.write( "x = 0 \n" ); document.write( ". \n" ); document.write( "Then plug the x value back into one of the equations: \n" ); document.write( "y = 4(0) + 0 \n" ); document.write( "y = 0 \n" ); document.write( ". \n" ); document.write( "So your answer would be (0,0) \n" ); document.write( "They intersect at the origin \n" ); document.write( " \n" ); document.write( " |
