Answer:

y = 5 and x = -3

Step-by-step explanation:

Given,

y = x + 8      ...............( equation 1 )  

x + y = 2      ...............( equation 2 )

Now,  by substituting the value of y in equation 2, we get;

⇒ x + x + 8 = 2

⇒ x = -3

and now, by substituting the value of x in equation 1, we get;

⇒ y = -3 + 8

⇒ y = 5

Oksanka [162]

Answer:

7/10

Step-by-step explanation:

To find the probability that a student is a liberal arts or female, we have to add together all of the people who were female or liberal arts majors in the study. If we add those together, (15 + 18 + 17 + 20) we get 70. 70/100 can be simplified to 7/10.
