Step 2.1

Subtract $\frac{7}{b}$ from both sides of the equation.

$4 a + 2 c + \frac{5}{d} + 6 e = 47.2506 - \frac{7}{b}$

Step 2.2

Subtract $2 c$ from both sides of the equation.

$4 a + \frac{5}{d} + 6 e = 47.2506 - \frac{7}{b} - 2 c$

Step 2.3

Subtract $\frac{5}{d}$ from both sides of the equation.

$4 a + 6 e = 47.2506 - \frac{7}{b} - 2 c - \frac{5}{d}$

Step 2.4

Subtract $6 e$ from both sides of the equation.

$4 a = 47.2506 - \frac{7}{b} - 2 c - \frac{5}{d} - 6 e$

Step 2.5

Subtract $6 e$ from $47.2506$ .

$4 a = - \frac{7}{b} - 2 c - \frac{5}{d} + 30.94090902$
