Here is how to solve this:
18 +4 = 22 bulls
45 + 4 = 50 cows
The original ratio was, 18:45 but now its 22:50 so, no the ratio will not be the same.

I think it's 60 I'm NOT sure. I just multiplied those three numbers
2nd subtraction property.
Add 7 on both sides to then left side cancels out and you end up with 13x=143 then you divide 13 on both sides and get x=11
