Question

x = 19 is a solution for the equation 14 + x = 36 true or false

Answer 1

We replace the value of x with the value 19 and, if the result is an identity, then x=19 is a solution:

$\begin{gathered} 14+x=36 \\ 14+19=36 \\ 33\ne36 \end{gathered}$

As the result is not an identiy, x=19 is not a solution to the expression.

Answer: False.
