0 is a solution of the equation x + 1 = 0
Idea: A solution of an equation is a value of x that makes the left side equal the right side.
Given equation:
\(x + 1 = 0\)
Check the value \(x = 0\):
Substitute:
\(x + 1 = 0 + 1\)
\(= 1\)
Now compare sides:
LHS \(= 1\)
RHS \(= 0\)
Since \(1 \neq 0\), the equation is not true for \(x = 0\).
Therefore, 0 is not a solution.
(For your understanding: the value that makes it true is \(x = -1\) because \((-1) + 1 = 0\).)
