Answer:

The number of points Kelly scored during the competiton for her arrows that landed in the ring sorrounding the bull's-eye is 27

Step-by-step explanation:

To get the number of points Kelly scored during the competiton for her arrows that landed in the ring sorrounding the bull's-eye, we solve the given equation

x + y = 41 ..........................................................(1)

4x + 7y = 206 ..................................................(2)

x is the value we are looking for.

From (1)

y = 41 - x

Substituting this into (2)

4x + 7(41 - x) = 206

4x + 287 - 7x = 206

4x - 7x = 206 - 287

-3x = -81

3x = 81

x = 81/3 = 27
