Question

Solve for a. 1/a+1/2a=1/a-3 a = 3 a = -3 a = 9 a = -9

Answer 1

Answer:

1/a+1/2a=-9

3/a=-9

a=-1/3

Answer 2

Answer:

$a = 9$

Step-by-step explanation:

$\frac{1}{a} + \frac{1}{2a} = \frac{1}{a - 3}$

$\frac{2a + a}{2 {a}^{2} } = \frac{1}{a - 3}$

$\frac{3a}{2 {a}^{2} } = \frac{1}{a - 3}$

$\frac{3 \times a}{2 \times a \times a} = \frac{1}{a - 3}$

$\frac{3}{2a} = \frac{1}{a - 3}$

$2a = 3a - 9$

$3a - 2a = 9$

$a = 9$
