19.Which number is in ? 9 4?6 2=4 1 + 2 3 4 X с C ·|· - -​

Sagot :

Answer:

2

Step-by-step explanation:

To solve the equation 9 - 4?6 - 7 = 2:

9 - 4 * 6 - 7 = 2

9 - 24 - 7 = 2

2 - 7 = 2

-5 = 2

The missing number must be 3, because when we substitute the missing number as 3 in the equation, we get:

9 - 4 * 3 - 7 = 2

9 - 12 - 7 = 2

5 - 7 = 2

-2 = 2

This makes both sides of the equation equal to 2, which is the correct answer.
