Let x be the number of dime then the number of quarter will be 35-x
1 dime = 10 c & 1 quarter = 25 c, so
(x*10)+(35-x)(.25) = 575
-15x = -300
15x = 300 & x = 20 (dime) & Quarter = 15

Step-by-step explanation:
Plug x for y and y for x.
y = 2x^2 + 2
x = 2y^2 + 2
Then isolate the y variable.
x - 2 = 2y^2
sqrt(x - 2) = 2y
(sqrt(x - 2))/2 = y
