Unless I am mistaken, the two numbers you are looking for are 36 and 34.

34 x 36 = 1224

34 + 36 = 70

Let x = first number

Let y = second number

x * y = 1224

x + y = 70

Express y in terms of x to eliminate 1 variable:

y=1224/x

The second equation can be written as

x + (1224/x) = 70

Multiply both sides by x

x^2 + 1224 = 70x

subtrace 70x from both sides

x^2 - 70x + 1224 = 0

Factor or solve the quadratic.
