Dory: $11.25= x+x+x+y+y+y or $11.25= (3*x)+(3*y)
Nemo: $10.00=x+x+x+x+y+y or $10.00= (4*x)+(2*y)

I hope this helps you
x= 5-7
x= -2
3.(-2)+2
-6+2
-4
X^2 - 4 x = -2
Add 4 to both sides:
x^2 - 4 x + 4 = 2
Write the left-hand side as a square:
(x - 2)^2 = 2
Take the square root of both sides:
x - 2 = sqrt(2) or x - 2 = -sqrt(2)
Add 2 to both sides:
x = 2 + sqrt(2) or x - 2 = -sqrt(2)
Add 2 to both sides:
Answer: x = 2 + sqrt(2) or x = 2 - sqrt(2)
