Question

3/5j-15=30 (by balancing method) ​

Answer 1

Answer:

j = 1/75

Step-by-step explanation:

Solving the equation using balancing method...

The equation given:

$\frac{3}{5j } - 15 = 30$

$\frac{3}{5j} - 15 + 15 = 30 + 15$

$\frac{3}{5j} = 45$

$\frac{3}{5j} \times 5j = 45 \times 5j$

$3 = 225j$

$\frac{3}{225} = \frac{225j}{225}$

$j = \frac{1}{75}$

Verification:

$\frac{3}{5 \times \frac{1}{75} } - 15 = 30$

$\frac{3}{5 \times \frac{1}{75} } = 45$

$\frac{3}{ \frac{1}{15} } = 45$

$3 \times 15 = 45$

$45 = 45$

L.H.S = R.H.S

Hence j = 1 / 75

Hope this helps !
