Algebra.Com's Answer #505972 by thejackal(72)![]() ![]() You can put this solution on YOUR website! important to remember that if they are consecutive even then the second number will be 2 + the first number. \n" ); document.write( "So let our two numbers be x and y. y is therefore really x + 2;\r \n" ); document.write( "\n" ); document.write( "Now we want to choose and x and consequently a y such that x times 5 is exactly 54 larger than 3 times y;\r \n" ); document.write( "\n" ); document.write( "this can be first expressed like so: 5x > 3y by 54; write this properly it becomes 5x > 3(x + 2) + 54; turn this inequality into an equation by subtracting 54 from both sides to get;\r \n" ); document.write( "\n" ); document.write( "5x - 54 = 3x + 6\r \n" ); document.write( "\n" ); document.write( "solve for x\r \n" ); document.write( "\n" ); document.write( "5x - 3x = 6 + 54 which when simplified becomes 2x = 60 thus x = 30\r \n" ); document.write( "\n" ); document.write( "now to find y we go back to our original equation for it x + 2 = 30 + 2 = 32\r \n" ); document.write( "\n" ); document.write( " \n" ); document.write( " |
