The two numbers are 41 & 37.
The way to solve this is by setting up an equation. We know that 2 numbers are going to equal 78, so here would be the general equation (let x represent the number we don't know):
(x) + (x + 4) = 78
Now, we need to simplify it (combine like terms):
2x + 4 = 78
Then you can solve it like any other equation. Subtract 4 on both sides:
2x = 74
Divide by 2 on both sides:
x = 37.
So, now you know one number is equal to 37 and that the other is 37 + 4.
That's how you get 37 & 41.
X = ?
X +4= ?
(X+4) + x = 78
2X + 4 = 78. Subtract 4 from both sides
You get 2X = 74. Divide both sides by 2 and you get x= 37
Now plug 37 in and you get 37 and 41
