7-x-(25+7)=9-25

To solve this equation, we need to simplify both sides of the equation and then isolate the variable x.

First, let's simplify the left side of the equation:

7-x-(25+7) = 7-x-32

Next, let's simplify the right side of the equation:

9-25 = -16

Now, we can rewrite the equation as:

7-x-32 = -16

To isolate the variable x, we need to get rid of the constants on the left side of the equation. We can do this by adding 32 to both sides:

7-x-32+32 = -16+32

Simplifying further:

7-x = 16

Finally, to solve for x, we can subtract 7 from both sides:

7-x-7 = 16-7

Simplifying further:

-x = 9

To solve for x, we can multiply both sides by -1:

(-1)(-x) = (-1)(9)

Simplifying further:

x = -9

Therefore, the solution to the equation is x = -9.
