2y − x = 6
Which statement is true about the coordinates of the point that is the solution to the system of equations?
A. It is (−2, 2) and lies on both lines.
B. It is (−5, 3) and lies on both lines.
C. It is (−5, 3) and does not lie on either line.
D. It is (−2, 2) and does not lie on either line.
3y+x=4
2y-x=6
Solve x+3y=4 for x
Add -3y to both sides
x+3y-3y=4-3y
x=-3y+4
Substitute -3y+4 for x in -x+2y=6
-x+2y=6
-(-3y+4)+2y=6
Simplify both sides of the equation
5y-4=6
Add 4 to both sides
5y-4+4=6+4
5y=10
Divide both sides by 5
5y/5=10/5
y=2
Substitute 2 for y in x=-3y+4
x=-3y+4
x=(-3)(2)+4
x= -6+4
x= -2
Answer : x=-2 and y=2
The answer is A
it is (-2,2) and lies on both lines
I hope that's help !

5% of $89.95 is $4.4975. After subtracting this discount from the original price, the DVD player costs $85.4525. Rounded to the nearest cent, the final price is $85.45.
To find the cost of the $89.95 DVD player after a 5% discount, we need to first figure out how much 5% of $89.95 is. This is done by multiplying $89.95 by 0.05 (which is the decimal equivalent of 5%).
So, $89.95 * 0.05 = $4.4975. This is the amount of the discount.
Now, to find the final price after the discount, we subtract the discount from the original price. Therefore, $89.95 - $4.4975 = $85.4525.
However, we need to round this to the nearest cent, which makes it $85.45.
