Answer: (x + 1/5).
Explanation:
To solve the equation 22 - 10x + 25 = 49, we first need to simplify it by combining like terms. We can do this by adding 22 and 25 to get 47. So, the equation becomes:
-10x + 47 = 49
Next, we need to isolate the variable term by subtracting 47 from both sides of the equation:
-10x = 2
Finally, we can solve for x by dividing both sides of the equation by -10:
x = -2/10
Simplifying this expression gives us:
x = -1/5
Therefore, the blank in (x - …) = 49 should be filled with (x + 1/5).
