Question
The equations x + 1 = 0 and 2x + 2 = 0 have the same solution.
Options
True
False
Solution
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.
