It means reduce it down to the easiest equation that makes the most sense.
Answer:
-3/2
Step-by-step explanation:
Here we have an ambiguous notation. Hence, I assume you mean (-12/((3 x (-8+ (-4)^2 -6) +2), which is the one that makes more sense.
First, we work the arithmetic on the denominator (D).
D= 3 x (-8 + (-4)^2 - 6) + 2
D=3 x (-8 + (-4) x (-4) -6) + 2
D= 3x (-8 +16 -6) + 2
D= 3 x (2) + 2=6 + 2=8
Now, we just have to divide -12 by D to obtain the answer.
-12/D = -12/8 =(-2 x 2 x 3)/(2 x 2 x 2) = -3/2
X=2t
y=1-t
t=x/2
y=1-x/2
y=(-1/2)x+1
price - (1/4)×price = price×(1 - 1/4) = (3/4)×price
... = (3/4)×5.90 = 4.425 ≈ 4.43 . . . . . sale price
_____
The sale price could be 4.42 if the discount is rounded up, rather than the price being rounded up. If you first compute the discount as (1/4)×5.90 = 1.475 ≈ 1.48, then the half-penny goes to the customer, not the shop-keeper.
