To solve the equation, we can start by simplifying both sides:

58 - 120 - x = -35 - 64

Combine like terms:

-62 - x = -99

Next, we can isolate the variable x by adding 62 to both sides:

-62 - x + 62 = -99 + 62

Simplifying further:

-x = -37

Finally, we can solve for x by multiplying both sides by -1:

(-1)(-x) = (-1)(-37)

x = 37

Therefore, the solution to the equation is x = 37.
