Question

9.4 + ___ = 3.2z - 4.5 + ___ What am I adding to both sides?

Answer 1

To solve the equation 9.4 + ___ = 3.2z - 4.5 + ___, you would need to add the same value to both sides in order to keep it balanced. This will help you eliminate the blank spaces and simplify the equation.

Step-by-step explanation:

To solve the equation 9.4 + ___ = 3.2z - 4.5 + ___, we need to add the same value to both sides of the equation in order to keep it balanced. By doing so, we can eliminate the need for the blank spaces. In this case, since there are two blank spaces, we need to find a single value that we can add to both sides. Let's call this value 'a'.

So, the equation becomes:

9.4 + a = 3.2z - 4.5 + a

Now, we can simplify the equation by combining like terms:

9.4 + a - a = 3.2z - 4.5 + a - a

Simplifying further:

9.4 = 3.2z - 4.5

By subtracting 9.4 from both sides, we isolate the variable 'z' on one side of the equation:

9.4 - 9.4 = 3.2z - 4.5 - 9.4

Finally:

0 = 3.2z - 13.9

This is the simplified equation after adding the same value to both sides.
