Answer:
Yes, those equations can be solved by adding one of the original equations to the other. And the solution is x = 1 and y = -2
Explanation:
The given equations are
4x - 2y = 8 ......... (1) and
12x + 2y = 8 .......... (2)
Now, those two equations can be solved by adding one of them to another.
So, by adding equations (1) and (2) we get,
(4x + 12x) = 8 + 8 = 16
⇒ 16x = 16
⇒ x = 1
Again, from equation (1) we get, 4(1) - 2y = 8
⇒ 2y = 4 - 8 = - 4
⇒ y = - 2
Hence, the solution is x = 1 and y = -2. (Answer)
