Quizplus · Accepted Answer

Simplifying the equation we get:
3p = 21p + 28
-18p = 28
p = -28/18 which simplifies to -14/9.
Therefore, B is the correct choice. Starting with the given equation:

3p = 7(3p + 4)

Distribute the 7:

3p = 21p + 28

Subtract 21p from both sides:

-18p = 28

Divide by -18:

p = -28/18

Simplify the fraction by dividing numerator and denominator by their greatest common factor (2):

p = -14/9

Therefore, the correct answer is B.

Solve the Equation. -3p = 7(3p + 4)
