Algebra.Com's Answer #463624 by blueplanet(7)![]() ![]() You can put this solution on YOUR website! Both equations can be solved by equating their real parts and by equating their imaginary parts.\r \n" ); document.write( "\n" ); document.write( "To solve 3x + (y-2)i = (5-2x) + (3y-8)i, we can approach the problem by equating the real parts first:\r \n" ); document.write( "\n" ); document.write( "3x = 5-2x \n" ); document.write( "=> x=1\r \n" ); document.write( "\n" ); document.write( "Then, equating the imaginary parts, we get:\r \n" ); document.write( "\n" ); document.write( "y-2 = 3y-8 \n" ); document.write( "y = 3\r \n" ); document.write( "\n" ); document.write( "So, (x,y) = (1,3).\r \n" ); document.write( "\n" ); document.write( "You can use a similar approach to resolve (x + iy)2 = 3+4i. If my calculation is correct, the answer should be (x,y) = (3/2, 2). \n" ); document.write( " \n" ); document.write( " |
