im confused, what is it that you are asking?
Let the numbers be x and y
x= y-2.... (1)
and, 2y = 16 + 4x.... (2)
putting the value of x from (1) in (2),
2y = 16 + 4x
=> 2y = 16 + 4(y-2)
=> 2y = 16 + 4y - 8
=> 2y = 8 + 4y
=> 2y - 4y = 8
=> -2y = 8
=> y =-8/2
=> y= -4
and x = -4-2 = -6
hence , in short the numbers are -2 and -4
Answer:
A.
Step-by-step Explanation:
P(A or B) = P(A)+P(B)-P(A and B)
Now
Putting the givens
0.68 = 0.2 + P(B) - 0.12
P(B) = 0.68 - 0.2 +0.12
P(B) = 0.6
