Answer:
x = - 3
y = - 2
Step-by-step explanation:
Start with the second equation. Switch
3y = 2x Divide by 3
3y/3 = 2x/3
y = 2x/3
Now go to the first equation. Put the value for y in the first equation.
x - 3(2x/3) = 3 Cancel the 3s on the left.
x - 2x = 3 Combine
-x = 3 Multiply by -1
-1(-x) = 3(-1)
x = - 3
Now go back to the original equation I have called the second equation
2x = 3y
2(-3) = 3y Put in - 3 for x
- 6 = 3y Divide by 3
-6 / 3 = y
y = - 2
Answer:
the probability that it is not a drama movie is 15/23
Step-by-step explanation:
To calculate the probability we have to make the number of favorable events divided the number of possible events
number of possible events = x
to calculate it we add all the movies
x = 10 + 5 + 8
x = 23
number of favorable events = y
to calculate it we subtract the drama movies from the total of movies
y = x - 8
y = 23 - 8
y = 15
now we divide 15 by 23 and we get the probability
15/23
