10

42_9=43

42-9=43-

42-9=43-

To find the missing number in the equation 42-9 = 43-, we first need to understand the pattern or rule that is being applied to the numbers.

In this case, let's analyze the equation: 42-9 = 43-

It appears that both sides of the equation involve subtraction. Looking at the first part of the equation, 42-9, we subtract 9 from 42 to get a result of 33. Now, we can use this result to understand the pattern.

If we subtract the same number from 43, we should get the same result as the first part of the equation, which is 33. Thus, we need to determine what number needs to be subtracted from 43 to get 33.

To find this missing number, we can set up an equation:

43 - x = 33

Here, 'x' represents the missing number. To solve for 'x', we need to isolate it by moving everything else to the other side of the equation:

43 - 33 = x

Simplifying the equation gives us:

10 = x

So, the missing number in the equation 42-9 = 43- is 10.
