No it's not an exponential equation in which f(x)is not qualified to an exponential number. no number from 1 - 20 can be used and get subtracted by 2 to give a square number.
eg-
4×2-2≠ square number
Solve y: 6.3 = 0.9y
6.3/0.9 = 0.9y/09
y = 7
Solve x: x + 7.72 = 19
x + 7.72-7.72 = 19 - 7.72
x = 11.28
What is y? 7 What is x? 11.28
10:40 because yellow goes before the total. Or it is 25%
