Ok you must do the inverse of division which is multiply
They aren't necessarily equal because, for example, 3/2 = 1 remainder 1 and 5/4 = 1 remainder 1 aren't equal because it takes 2 x 1 = 2 + 1 = 3 while 4 x 1 = 4 + 1 = 5. They are the same quotient and remainer, except they aren't used to check if it multiplys back to the same divended.
Answer:
x= 3. y = 3
Step-by-step explanation:
-3x + 7y = 12. #1
x - 2y = -3. #2
Multiply Eqtn #2 by 3 and add the two together:
-3x + 7y = 12
3x - 6y = -9
or. y = 3
Plug this value into Eqtn #2 and you'll get
x = 3
Answer:

I don't really know about hope this help
Answer:
1 -4i
Step-by-step explanation:
1-sqrt(-16)
We know that sqrt(ab) = sqrt(a) sqrt(b)
1 - sqrt(16) sqrt(-1)
Assuming we take the principal value of the square root
The square root of -1 is i
1 -4i
