What is the value of w?
5( 9 - 3) = w x 9 - 5 x 3
I think the answer is 6 because 9-3 equals 6. *it's not multiple choice*
Remember PEMDAS

5( 9 - 3) = w x 9 - 5 x 3
30 = 9w - 15
45 = 9w
5 = w
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
Proof:
30 = 45 - 15
Thanks Ms. Sue! I have some more questions to ask.
You're welcome, Nay.
To solve for the value of w in the equation 5(9-3) = w * 9 - 5 * 3, we need to simplify both sides of the equation first.
Starting with the left side of the equation:
5(9-3) = 5 * 6 = 30
Now let's simplify the right side of the equation:
w * 9 - 5 * 3 = 9w - 15
We can set the two sides of the equation equal to each other:
30 = 9w - 15
Next, we can isolate the variable w by adding 15 to both sides of the equation:
30 + 15 = 9w - 15 + 15
45 = 9w
Finally, to solve for w, we divide both sides of the equation by 9:
45 / 9 = 9w / 9
5 = w
Therefore, the value of w is 5, not 6.
