Answer:
0=0
Step-by-step explanation:
-2(x-6)=-2x+12
-2x+12=-2x+12 /+2x
12=12 /-12
0=0 which means x can be any number.

14
Step-by-step explanation:
im ur teacher what are u doing
Answer:
put -2 in -2 / put -2 again in same spot and again just do it for 3 times then 1/3 in the middle of 0 and -2 but a bit closer to the -2
Step-by-step explanation:
For the first one, if you add 2 equations together, you will get:
4 = 4, which is trivial, irrelevant to x. So it means it has infinite solutions
For the second one, if you add them up, you will get 0 = 12, which is incorrect, and irrelevant to x as well. So it means it has no solutions
