2 minus what # is 5

2 minus what number equals 5?

The missing number is -3.

To find the number that, when subtracted from 2, results in 5, you can set up the equation:

2 - x = 5

To solve for x, you need to isolate it on one side of the equation.

First, subtract 2 from both sides of the equation:

2 - 2 - x = 5 - 2

Simplifying:

0 - x = 3

Since any number subtracted from 0 is still that number, the equation becomes:

-x = 3

To isolate x, you can multiply both sides of the equation by -1:

(-1) * (-x) = (-1) * 3

Simplifying:

x = -3

Therefore, the number you are looking for is -3.

To find the number you need to subtract from 2 to get 5, you can set up an equation:

2 - x = 5

To solve for x, you need to isolate it on one side of the equation. Start by subtracting 2 from both sides:

2 - 2 - x = 5 - 2
0 - x = 3

Next, simplify the equation:

-x = 3

To solve for x, you need to multiply both sides of the equation by -1 to cancel out the negative sign:

(-1)(-x) = (-1)(3)
x = -3

Therefore, the number you need to subtract from 2 to get 5 is -3.
