It would be the first answer. Bubble. I don't know what you call it. But yeah, it's the first one.
In system A, the first equation multiply by 4
8x - 4y = 12 (1st)
3x + 4y = 10 (2nd)
--------------------add
11x = 22
So answer is B.
Answer:
6 x 4 you have 4 numbers and each can be put in 6 different ways. so it is 24 i think
Step-by-step explanation:
C, because when you add 45 on both sides, and then after that when you have to subtract 15 in both sides, you get 0 = 120.
It is 9/10 as the others are too small
