Question

7. Which of the following equations can be formed starting with x = 0?
A. 2x + 1 = -1 B. x2 + 5 = 7
B. XI 2 + 5 = 7 C. 3x – 1=-1 D. 3x – 1 = 1​

Answer 1

Answer:

d.3x-1=1

Step-by-step explanation:

The equation that has x=0 as a solution can be formed starting with x=0.

Solving the given equations for x

(a) 2x+1=−1

⇒2x=−1−1

⇒2x=−2

⇒x=−1

(b)

2

x

+5=7

⇒

2

x

=7−5

⇒

2

x

=2

⇒x=4

(c) 3x−1=−1

⇒3x=1−1

⇒3x=0

⇒x=0

(d) 3x−1=1

⇒3x=1+1

⇒3x=2

⇒x=

2

3

Hence, option (D) is correct as it has x=0 as a solution.
