If the first number is multiplied by 4, the result is 9 less than the sum of the other two. find all three numbers. : WE can call it 2x; 4x; 7x without changing the ratio 1st number = 2x 2nd number = 4x 3rd number = 7x : Write an equation for: "If the first number is multiplied by 4, the result is 9 less than the sum of the other two." 4(2x) = 4x + 7x - 9 8x = 11x - 9 8x - 11x = -9 -3x = -9 x = + 3 : Our three numbers: 2(3) = 6 4(3) = 12 7(3) = 21
