Question

What is the solution to
(y = 3x - 30
x2 + y2 = 100

Answer 1

Answer:

x = 20

y = 30

Step-by-step explanation:

Answer 2

Answer:

x = 20

y = 30

Step-by-step explanation:

y = 3x - 30

2x + 2y = 100

2x + 2(3x - 30) = 100

2x + 6x - 60 = 100

8x - 60 = 100

8x = 160

x = 20

y = 3(20) - 30

y = 60 - 30

y = 30
