From equation 1
x = -3y-13
plug this into equation 2:-
5(-3y-13) + 7y = -9
-15y - 65 + 7y = -9
-8y = 56
y = -7
Now plug y = 7 into equation 1
x - 21 = -13
x = -13 + 21 = 8
solution is x = 8 , y = -7

Answer:
-19 1/9
Step-by-step explanation:
Using it's concept, it is found that the probability that he winds up wearing the white shirt and tan pants is of
.
<h3>What is a probability?</h3>
A probability is given by the <u>number of desired outcomes divided by the number of total outcomes</u>.
In this problem:
- For the shirt, there is 4 outcomes, hence the probability of the white shirt is 1/4.
- For the pair of pants, there are 2 outcomes, blue or tan, hence the probability of tan pants is 1/2.
Since the shirt and the pants are independent, the probability is given by:
