Question

7. What is the value of x? −4x − 6 = −34 A. −10 B. −7 C. 7 D. 10

Answer 1

-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
