2 minus what equals 7?
Here we will show you how to calculate "2 minus what equals 7?" using simple algebra.
For the math problem, "2 minus what equals 7?", we can make it into an algebra equation as follows:
2 - X = 7
Then, we solve for X. To solve for X, we first subtract 2 from both sides:
2 - 2 - X = 7 - 2
-X = 5
Next, you multiply each side by -1 to remove the minus from the X:
-X(-1) = 5(-1)
X = -5
Therefore, the answer to "2 minus what equals 7?" is -5 as illustrated below:
2 - (-5) = 7
