Y= 12 - x
27 + 3( 12 - x ) = 2x
I believe it's 2160. Sounds right to me
Answer:
u = 94
Step-by-step explanation:
First multiply both sides of the equation by 2.
·2 = 6·2
u - 82 = 12
Then add 82 to both sides of the equation
u - 82 + 82 = 12 + 82
This gives you your answer.
Hope this helps!

P(A) = 5/10
P(B|A) = 4/9
P = 5/10 * 4/9 = 20/90 = 2/9
In this problem why is the easiest to substitute.
Just set the equations equal to each other because they both equal y
-x + 4 = 2x - 8
(You want to get all the x's to one side so add x to each side)
4 = 3x - 8
(next add 8 to both sides)
12 = 3x
(lastly divide 3 from both sides)
4 = x
You have got your x so now it is time to find that y just replace x to either of the two equations
y = 2(4) -8 or y = -(4) + 4
y = 8 - 8 y = 0
y = 0
Final Answer: y=0, x=4
