first number - X 2nd number - X 3rd number - Y 4th number - 2X 5th number - 2Y. given that X+X+Y+2X+2Y = 18. wch gives 4X+3Y = 18. using trial nd error, let X values range from 1,2,3,4,… X as 1 nd 2 gives Y as fractions, so unacceptable. so the lowest digit of X that gives Y as whole number is 3. I. e 4(3)+3Y =18. therefore, Y = 2,when X=3. X+X+Y+2X+2Y = 18. 3+3+2+6+4(33264) 1 Like |
