Question

so in my kid homework notebook this is a problem that we cannot understand 45-___=39
(I feel so old asking this)​

Answer 1

Answer: 6

Step-by-step explanation:

For the math problem, "45 minus what equals 39?", we can make it into an algebra equation as follows:

45 - X = 39

Then, we solve for X. To solve for X, we first subtract 45 from both sides:

45 - 45 - X = 39 - 45

-X = -6

Next, you multiply each side by -1 to remove the minus from the X:

-X(-1) = -6(-1)

X = 6

Therefore, the answer to "45 minus what equals 39?" is 6 as illustrated below:

45 - 6 = 39

Answer 2

Answer:

Hello. The answer is 6.

Step-by-step explanation:

You basically have to subtract. 45 - (?) = 39.

45 - 6 will give you = 39.

I'm surprised even an adult doesn't know that?
