Ok let's translate question mathematically.
Let x be first number
y be second number
z be third number
So this question says
y = 2x
z = 2+5x
y+z = 37
So we need so solve those equations.
Use first and second into third:
(2x) + (2+5x) = 37
7x + 2 = 37
7x = 35
x = 5
Now plug x value into first and second equation:
y = 2(5)
y = 10
z = 2+5(5)
z = 2+25
z = 27
So the answer is
First number is 5, second number is 10, and third number is 27
