Answer:
the numbers are 7 and 11
Step-by-step explanation:
If you add the smaller to the sum of numbers, you have the sum of the greater and twice the smaller. That is ...
18 + smaller = 25
smaller = 25 -18 = 7
larger = 18 -7 = 11
The two numbers are 7 and 11.
_____
If you like, you can write two equations. Let x and y represent the smaller and larger numbers, respectively.
x + y = 18
2x + y = 25
Subtract the first equation from the second:
(2x +y) -(x +y) = (25) -(18)
x = 7
y = 18-x = 18-7 = 11
The numbers are 7 and 11.

Answer:
A is the correct answer
Step-by-step explanation:
To get the fastest answer for these kind of questions, you just have to apply (0, -2) into either one of the 2 equations:
2 * 0 - 6 * (-2) = 12
0 - (-12) =12
0 + 12 = 12 (TRUE)
So the solution will be (0, -2)
