Answer:
x=-5, y=-11
Step-by-step explanation:
When approaching systems of equations, you must either solve via subsitution or through manipulation to get one term aglebraically; either way, you want to solve for one variable at a time. So, we have
Multiply line A by (3) and then add it on to Line B. From there break it down and sub in what you get for y into either equation.

Answer:
Let us first jot down all the data given in the question;
Number of low quality computers (LQ) = 72
Number of medium quality computers (MQ) = 112
Number of high quality computers (HQ) = 711
∴ Total number of computers found in a random sample = 72 + 112 + 711 = 895.
∴ To find the probability of purchase for each category of computers, we use the following formula;
So,
P(LQ) = 72/895 = 0.08
P(MQ) = 112/895 = 0.125
P(HQ) = 711/895 = 0.794
Ans) Probability of purchase of a low quality computer, a medium quality computer, and a high quality computer are 0.08, 0.125, and 0.794 respectively
