Why?
To know the solution of the problems, we need to isolate each variable.
Remember that:
- If we have an equality: if the number is part of a product , and if you need to move it to the other side of the equality, the same number will be dividing the factors of the side.
- If we have an equality: if the number is subtracting (negative sign), and if you need to move it to the other side of the equality, its sign changes to positive.
- If we have an equality: if the number is adding (positive sign), and if you need to move it to the other side of the equality, its sign changes to negative.
- The distributive property states that:

So,
1 - Solving for p

2 - Solving for t

3 - Solving for x

4 - Solving for x
