One number is 77 times a first number. A third number is 100 more than the first number. If the sum of the three numbers is 883 , find the numbers

X = first number = 9.91

77x = second number = 763.07

x + 100 = third number = 109.91

x + 77x + x + 100 = 883

79x + 100 = 883

-100 - 100

79x = 783

/79 / 79

x = 9.91 (rounded to nearest hundreth)

77 (9.91) = 763.07

9.91 + 100 = 109.91
