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
