Question 46

Question. 46

2x – 5 > 11 is an equation.

Answer:

false

Detailed Answer with Explanation:

Why the statement is False:

Equations always use the equals sign “=” and say that two sides are the same.

Example of an equation: \(2x - 5 = 11\)

Inequalities use signs like “\(>\)”, “\(<\)”, “\(\ge\)”, or “\(\le\)”. They compare two sides but do not say they are equal.

Given statement: \(2x - 5 > 11\) — this uses “\(>\)”, so it is an inequality, not an equation.

Quick contrast (optional):

If it were an equation, it would be: \(2x - 5 = 11\)

Solving that would give one exact value:

\(2x - 5 = 11\)

\(2x = 11 + 5\)

\(2x = 16\)

\(x = 8\)

But our actual statement is an inequality:

\(2x - 5 > 11\)

\(2x > 11 + 5\)

\(2x > 16\)

\(x > 8\)

Conclusion: Because it uses “\(>\)” instead of “\(=\)”, \(2x - 5 > 11\) is an inequality, not an equation. Therefore, the statement “2x – 5 > 11 is an equation” is false.
