A) Numerical Sequence
    1) Finding Terms from a Table

To keep the scale balanced, any operation we perform must be done on both sides equally. To isolate \(x\), we need to remove the weight of 10 from the left pan. To maintain balance, we must also remove a weight of 10 from the right pan.
This process shows that \(x+10=13\) is equivalent to \(x=3\). A solution to an equation is a value for the variable that maintains the balance. Here, the solution is \(x=3\).
