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 \(6\).
