Answer:
4
Step-by-step explanation:The factors of 212 are: 1, 2, 4, 53, 106, 212
The factors of 312 are: 1, 2, 3, 4, 6, 8, 12, 13, 24, 26, 39, 52, 78, 104, 156, 312
First, multiply the first equation by 2.
That turns the first equation into:
6x - 2y = 18
That way it can easily be added to the second equation:
6x - 2y = 16
x + 2y = 5
---------------
7x = 21
==========
As you can see, the y disappeared, which was the objective of this operation.
Now the equations can be solved easily:
7x = 21
x = 3
Insert x=3 in the original equation:
3*3 - y = 8
9 - y = 8
9 = 8 + y
y = 1
So the result is:
x = 3
y = 1
Answer:
the answer should be 5/16
Answer:
y= -3x
Step-by-step explanation:
Do 12/16 which equals 0.75
0.75 is equal to 3/4
so the answer is 3/4
Hope this helps!
