-2-(3-х)=-7

To solve the equation -2-(3-x)=-7, we first need to simplify the expression inside the parentheses:

-2 - (3 - x) = -7 -2 - 3 + x = -7 -5 + x = -7

Next, we can isolate x by adding 5 to both sides of the equation:

x = -7 + 5 x = -2

Therefore, the solution to the equation -2-(3-x)=-7 is x = -2.
