Algebra.Com's Answer #196254 by ankor@dixie-net.com(22740) You can put this solution on YOUR website! how do i solve and write two equations: \n" ); document.write( " for the sum of two numbers is 30. \n" ); document.write( "x + y = 30 \n" ); document.write( ": \n" ); document.write( "the sum of the greater number and 3 times the lesser number is 54. \n" ); document.write( "x + 3y = 54 \n" ); document.write( "x + y = 30; subtract the 1st equation from the 2nd equation, eliminate x \n" ); document.write( "------------ \n" ); document.write( " 2y = 24 \n" ); document.write( "y = 12 \n" ); document.write( "then \n" ); document.write( "x = 30 - 12 = 18 \n" ); document.write( "; \n" ); document.write( ": \n" ); document.write( "Check solution in the statement \n" ); document.write( "\"the sum of the greater number and 3 times the lesser number is 54.\" \n" ); document.write( "18 + 3(12) = 54 \n" ); document.write( " \n" ); document.write( " |
