Question

Solve the equation 8d – 4d – 6d – 8 = 2d A. 0 B. -4 C. -2 D. -4

Answer 1

Hi there! The answer is C. - 2

$8d - 4d - 6d - 8 = 2d$
First we collect the terms.

$- 2d - 8 = 2d$
Next subtract 2d from both sides.

$- 4d - 8 = 0$
Add 8 to both sides.

$- 4d = 8$
Finally divide both sides by -4.

$d = \frac{8}{ - 4} = - 2$
Therefore, the answer is C. -2

~ Hope this helps you!

Answer 2

8d – 4d – 6d – 8 = 2d

Combine common terms:
-2d - 8 = 2d

Add 2d to both sides:
-8 = 4d

Swtich sides:
4d = -8

Divide both sides by 4:
d = -2

Answer: - 2
