Answer:
x = - 3
Step-by-step explanation:
Solve by isolating x on one side of the equation.
12x+12=8x
-12 -12
12x=8x-12
-8x
4x=-12
4x/4=-12/4
x = - 3
Answer: Second option: 8/21
Solution:
P(1) = (Number of times we get 1) / (Total number of results)
Number of times we get 1 = 8
Total number of results = 21
P(1)=8/21
X&y=1
4×1= 4+1=5
hope this helps
