Equations are more important to me, because politics is for the present, but an equation is something for eternity.

200 + 2x = 230. X=15

Owl equation

To solve for b, we can use the given equations:
1. a + b = 230
2. a - b = 200
We can solve these equations by adding them together:
(a + b) + (a - b) = 230 + 200
a + b + a - b = 430
2a = 430
a = 215

Now, substitute a = 215 back into the first equation to find b:
215 + b = 230
b = 230 - 215
b = 15
So, b = 15.
