Question

-4x+y=1

2y-2=8x

How many solutions does this have?

a. no solution
b. one solution
c. infinitely many solutions

Answer 1

Explanation:

y = 4x + 1

2y - 2 = 8x

2(4x + 1) - 2 = 8x

2x + 2 - 2 = 8x

2x + 0 = 8x

6x = 0

x = 0

y = 0 + 1

y = 1

(0, 1)

answer is b. one solution

Answer 2

c. infinotely msny solutions
