Although the options are not provided, the true statement is:
x = 5 is a true solution because log₂(16) = 4
In order to check if a solution is true, we may plug it back into the original equation. When we plug x into the equation we get:
log₂(5+11) = 4
log₂(16) = 4
4 = 4
As the left hand side of the equation is equal to the right hand side, the solution is true.
