Question

p(d + x) = 2x + 3
Which equation is correctly rewritten to solve for d?

Answer 1

Answer:

d = $\frac{2x + 3}{p}$  - x

Step-by-step explanation:

First divide both sides by p.

then subtract x from both sides

Step-by-step explanation:

Step 1: Define

Identify

$\displaystyle p(d + x) = 2x + 3$

Step 2: Solve for d

1. [Division Property of Equality] Divide p on both sides:                                  $\displaystyle d + x = \frac{2x + 3}{d}$
2. [Subtraction Property of Equality] Subtract x on both sides:                         $\displaystyle d = \frac{2x + 3}{d} - x$
