X * y = -48
x + y = 8
y = -48/x
x -48/x = 8
x^2 - 48 = 8x
x^2 - 8x -48 = 0
x = 12
y = -4
Answer with Step-by-step explanation:
Let F be a field .Suppose and
We have to prove that a has unique multiplicative inverse.
Suppose a has two inverses b and c
Then, where 1 =Multiplicative identity
(cancel a on both sides)
Hence, a has unique multiplicative inverse.
Answer:
8/19
Step-by-step explanation:
Use this rule: a b/c=ac+b/c
2x8+3/8
The answer is 5.
you can turn it into a fraction ratio (6 over 15 is equal to 2 over c) and then cross multiply
