Answer:
168.
Step-by-step explanation:
H.C.F. = 6 = 2 by 3.
L.C.M. = 280 = 2^3 by 5 by 7.
30 = 2 by 3 by 5.
x = 2^3 by 3 by 7 = 168.
I used the factorisation method.
Answer:
the correct answer is A : 2x3-1
We have

First, we can combine like terms 3y and -7y to get -4y.
Then, we have

We could then subtract 8 on both sides to get

Finally, we isolate y completely by dividing both sides by -4, to get
