Question 11(Multiple Choice Worth 5 points)

(03.06A LC)
Which statement is true for the equation 2x - 2x - 7 = -7?
O It has infinitely many solutions.
O It has two solutions.
O It has one solution.
It has no solution.

Answer 1

Answer: Option 'a' is correct.

Explanation:

Since we have given that

2x-2x-7=-7

We need to solve it first as follows:

`2x-2x-7=-7`

`2x-2x=-7+7`

`0=0`

Since L.H.S. = R.H.S.

So, it satisfies the equation for all x.

So, there will be infinitely many solutions.

Hence, Option 'a' is correct.
