Question

How many solutions does the equation –2(3x – 1) = –6x – 1 have?

What about 2(3x – 1) = 6x – 2?

What about 2(3x – 1) = –6x – 2?

Answer 1

Answer: See below

Explanation:

–2(3x – 1) = –6x – 1

-6x + 2 = -6x - 1 (IMPOSSIBLE, ZERO)

2(3x – 1) = 6x – 2

6x - 2 = 6x - 2 (INFINITE)

2(3x – 1) = –6x – 2

6x - 2 = -6x - 2 (ONE, x can be the number 0)
