-4x - 6 = -34

First, add '6' to both sides.
\(-4x = -34 + 6\)
Second, subtract '-34 + 6' to get '-28'.
\(-4x = -28\)
Third, divide both sides by '-4', leaving the 'x' by itself.
\(x = \frac{-28}{-4}\)
Fourth, simplify the fraction into a negative.
\(x = \frac{28}{4}\)
Fifth, how many times can 4 go into 28? Divide. 28 ÷ 4 = 7.
\(x = 7\)

Answer: C) x = 7
