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.

36 girls

step-by-step explanation:

the 48 boys is 4 parts of the ratio

divide 48 by 4 to obtain one part of the ratio

= 12 ← 1 part of the ratio

3 parts = 3 × 12 = 36 ← number of girls
