Question

For which equation is x = 1 not a solution?

A. 2x - 1 =1
B. 2x + 1 = 5
C. 3x + 2 = 5
D. 4x - 1 =3

Answer 1

OPTION B (2x + 1 = 5)

Explanation:

Let's list them:

Option A:

2(1) -1 = 1

2 - 1 = 1

1 = 1 (Satisfies Equation)

Option B:

2(1) + 1 = 5

2 + 1 = 5

3 = 5 (DOES NOT Satisfy Equation)

Therefore, this is the answer to your question!
