Answer: Use the distributive property to multiply 3 by y−4.
3y−12−2(y−4)
Use the distributive property to multiply −2 by y−4.
3y−12−2y+8
Combine 3y and −2y to get y.
y−12+8
Add −12 and 8 to get −4.
Anwser:
y−4

This is a classic example of a 45-45-90 triangle: it's a right triangle (one angle of 90) & two other sides of the same length, which means two angles of the same length (and 45 is the only number that will work). With a 45-45-90 triangle, the lengths of the legs are easy to determine:
45-45-90
1-1-sqrt2
Where the hypotenuse corresponds to sqrt2.
Now, your hypotenuse is 10.
To figure out what each leg is, divide 10/sqrt2 (because sqrt2/sqrt2 = 1, which is a leg length in the explanation above).
Problem: you can't divide by radicals. So, we'll have to rationalize the denominator:
(10•sqrt2)/(sqrt2•sqrt2)
This can be rewritten:
10sqrt2/sqrt(2•2)
=10sqrt2/sqrt4
=10sqrt2/2
=5sqrt2

Let's answer this step-by-step.
First of all, let's estsblish the original price of the commodity as being 100%. Therefore:
Original price of commodity = 100%
Then, when A sold the commodity to B, it was sold at a 10% profit. Therefore:
Price of commidity when A sold to B:
100% x 1.1 = 110%
After that, when B sold it back to A, it was sold at a 10% loss. Therefore:
Price of commodity when B sold to A:
110% x 0.9 = 99%
Hence, A now has 99% of the original value of the commidity.
