The answer is -17.875. To solve it you have to make x by itself.
-2(4x-13)- -7=176
First, you would have to distribute.
-8x+26+7=176
Next, you combine like terms.
-8x+33=176
To get x by itself you next have to get rid of the constant.
-8x=143
Then you get x by itself by dividing the coefficient out.
x=-17.875
