Given the following equation given in the exercise:
[tex]x-2=11[/tex]You need to solve for the variable "x" in order to find the solution. You can follow this procedure:
Apply the Addition property of equality and add 2 to both sides of the equation:
[tex]\begin{gathered} x-2+(2)=11+(2) \\ x=13 \end{gathered}[/tex]Remember that the Addition property of equality states the following (For any numbers "A", "B" and "C":
[tex]\text{If }A=B\text{ then }A+C=B+C[/tex]Threfore, you get that the answer is:
[tex]x=13[/tex]
