Solve for a 47.2506=4a+7/b+2c+5/d+6e

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

Step 1

Rewrite the equation as $4 a + \frac{7}{b} + 2 c + \frac{5}{d} + 6 e = 47.2506$ .

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

Step 2

Move all terms not containing $a$ to the right side of the equation.

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

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

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

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

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

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

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

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

Subtract $6 e$ from $47.2506$ .

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

Step 3

Divide each term in $4 a = - \frac{7}{b} - 2 c - \frac{5}{d} + 30.94090902$ by $4$ and simplify.

Divide each term in $4 a = - \frac{7}{b} - 2 c - \frac{5}{d} + 30.94090902$ by $4$ .

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