x=21 is the correct answer.
Further explanation:
In order to solve a linear equation, the variable has to be isolated on one side of the equation. Then the properties of equality are used to isolate the variable in the equation.
Given Equation is:
x-5 = 16
Addition property of equality states that if one number is added to right side of the equation, then it must be added to the left side of the equation too.
So, applying the property, adding 5 on both sides
[tex]x-5+5 = 16+5\\x = 21[/tex]
Hence, x =21
