Question 630726
Let x=the first number
   97-x= the second number 

The first number x is equal to 2 times the second number + 4, so the equation is

x=2(97-x)+4

x=194-2x+4       -- multiply 2 and (97-x), applying distributive property
x+2x=194-2x+4+2x --add 2x on both sides of the eqn
3x = 198         -- 194+4=198
(3x)/3 = 198/3   -- Divide both sides by 3

x=66       -------> the value of the first number
second number = 97-x
              = 97-66
              = 31

Answer: The two numbers are 66 and 31.
