Algebra.Com's Answer #445077 by jim_thompson5910(35256)![]() ![]() ![]() You can put this solution on YOUR website! y is already isolated. So you can plug in y = 2x - 5 into the second equation to get 4(2x-5) + 8x = 15\r \n" ); document.write( " \n" ); document.write( "\n" ); document.write( "Then you solve for x. After you get the value of x, you use it to find y (by plugging the solution you found for x into y = 2x - 5)\r \n" ); document.write( " \n" ); document.write( "\n" ); document.write( "So this all shows that substitution is the easiest to use in this problem. \n" ); document.write( " |
