The equation we use here is:
x is for the number of games he played on first day, y is the games on second day. The coefficients are the decimal form of percentages.
Simplify:
To find x we need to use the ratio. We have 85/100 as the first day's ratio and because the games needs to be whole, we can simplify this as 17/20. So in first day, he played at least 20 games and won 17 of them.
When we plug the 20 into the equation as x:
So he needs to play at least 30 games in order to get his score to 94%.

x = -1
Step-by-step explanation:
or
Since both sides have the same base, we can write
10x = 5x - 5
or
5x = -5
x = -1
