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 = (-28)/(-4)`
Fourth, simplify the fraction into a negative.

`x = (28)/(4)`
Fifth, how many times can 4 go into 28? Divide. 28 ÷ 4 = 7.

`x = 7`

Answer: C) x = 7
