Question

The equations x + 1 = 0 and 2x + 2 = 0 have the same solution.

पर्याय

• True

• False

Answer 1

This statement is True.

Explanation:

Given equations,

⇒ x + 1 = 0   ...(i)

⇒ 2x + 2 = 0  ...(ii)

From equation (i), x + 1 = 0

⇒ x = –1   ...[Transposing +1 to RHS]

From equation (ii), 2x + 2 = 0

⇒ 2x = –2   ...[Transposing +2 to RHS]

⇒ x = `(-2)/2`  ...[Dividing both sides by 2]

⇒ x = –1

Clearly, the solution of both the equation are same.
