What is the solution to this system of linear equations? 2x + 3y = 3 7x – 3y = 24 (2, 7) (3, –21) (3, –1) (9, 0)

The answer is that x = 3 and y = -1 or (3, -1)

Step-by-step explanation:

In order to find these values, we can use elimination. To do so, we simply add the two equations together.

2x + 3y = 3

7x - 3y = 24

9x = 27

x = 3

Now that we have this value, we can plug the value into one of the originals and find y.

2x + 3y = 3

2(3) + 3y = 3

6 + 3y = 3

3y = -3

y = -1

C.     (3, –1)

The person above offers a good explanation on how to get this answer.

the inequality is:

250c+180g≥950

step-by-step explanation:

let c denotes the number of days in a week   miyoko worked as a cryptographer.

and g denotes the number of days in a week she works as a geologist.

now we are given that she earns $250 for every day she works as a cryptographer,and earns $180 for every day she works as a geologist.

now miyoko's goal is to earn more than $950 this week.

hence, the inequality could be represented as:

250c+180g≥950

the answer is b.
