Question. 47

In an equation, the LHS is equal to the RHS.

Answer:

true

Detailed Answer with Explanation:

Step 1: What is an equation?

An equation is a math statement with an equal sign (=) in the middle.

It has two sides:

  • LHS = Left Hand Side (left of =)
  • RHS = Right Hand Side (right of =)

Step 2: What must be true in an equation?

For a statement to be an equation, both sides must have the same value.

That means: \(\text{LHS} = \text{RHS}\).

Step 3: See with a simple example

LHS: \(2 + 3\)

\(= 5\)

RHS: \(5\)

So, \(2 + 3 = 5\). Here, LHS and RHS are both \(5\), so they are equal.

Step 4: Another example with working

LHS: \(7 - 2\)

\(= 5\)

RHS: \(3 + 2\)

\(= 5\)

Since both sides are \(5\), \(7 - 2 = 3 + 2\) is an equation.

Important:

If LHS and RHS are not equal, then it is not a true equation.

For example:

LHS: \(4 + 1 = 5\)

RHS: \(10\)

Here, \(5 \neq 10\). So \(4 + 1 = 10\) is false.

Conclusion:

By definition, in an equation the Left Hand Side equals the Right Hand Side. So the statement is true.
