The formal name for the property
of equality that
allows one to add the same quantity to both sides
of an equation.
This is one
of the most commonly used properties for solving equations.
The formula tells us that if a = b, then a + c = b + c. The letters a and b stand for two separate numbers, our two twins, and the letter c
stands for what we give to each twin to keep them matching. So, for
example, if we add 1 to the left side of the equation, we must also add 1
to the right side of the equation. By doing this, we keep the equation,
the twins, the same.
Answer: correct choice is B.
The expression:
3 (x - 2)
indicates that the number 3 before the parenthesis is multiplying the expression inside the parenthesis.
Then in order to do such we use what is called the distributive property which tells us to "distrubute" suche multiplication among the two term that are in the parenthesis:
3 x - 3 * 2
3 x - 6
Which is the first option in your answer list.
