**Fill in the suitable values:**

**1.**____ \(+ 5 = 11\)

This can be done by trial and error method.

Let us substitute some values by our self and get the fit of it.

Let the unknown value is \(1\).

\(1+5 = 6\).

In the right side of the equation, we have \(11\). Thus, the value does not fit.

Let the unknown value is \(2\).

\(2+5 = 7\).

In the right side of the equation, we have \(11\). Thus, the value does not fit

Let the unknown value is \(3\).

\(3+5 = 8\).

In the right side of the equation, we have \(11\). Thus, the value does not fit.

Let the unknown value is \(4\).

\(4+5 = 9\).

In the right side of the equation, we have \(11\). Thus, the value does not fit.

Let the unknown value is \(5\).

\(5+5 = 10\).

In the right side of the equation, we have \(11\). Thus, the value does not fit.

Let the unknown value is \(6\).

\(6+5 = 11\).

In the right side of the equation, we have \(11\).

Thus the value satisfies the given equation.

Therefore the unknown value must be \(6\).
