^^^ this is correct, but bro it’s just simple subtraction. Use a calculator or sum
Answer:
x=0
y= -1
Step-by-step explanation:
x−2y=2 - eq 1
3x+2y=−2 - eq 2
x−2y=2
(3x+2y)+(x−2y)=−2+2
x−2y=2
3x+2y+x−2y=0
x=0
y= -1
The correct next step Amy could take is to factor (x^2 - 16) on the left side of the equation to yield (x + 4)(x – 4)(x + 2) = 0.
The equation is given as:

The possible next steps are:
1. Expand the equation as follows

2. Express x^2 -16 as a difference of two squares as follows

However, the correct step in this case is to factor x^2 - 16 as a difference of two squares to give 
This is so, because the question says Amy is trying to solve for variable x.
This step will ensure that she gets the possible values of x, unlike expanding the whole equation .
Hence, the correct next step is

Answer:
The answer is A: 5x + 10y > 30. That is, the combination of boxes must be greater than 30 since the requirement is to have more than 30 lb of nails.
Step-by-step explanation:
The worker can buy a combination of boxes, as long as the total is greater than 30 lb. Multiply 5 lb by x and add that to 10 lb times y to get the total, which must exceed 30 lb.
