Answer:

$x=-\frac{9}{4}$

Step-by-step explanation:

Step 1: Subtract 21 from both sides

$8x + 21 = 3$

$8x + 21 - 21 = 3 - 21$

$8x = -18$

Step 2: Divide 8 from both sides

$8x = -18$

$\frac{8x}{8}=-\frac{18}{8}$

$x=-\frac{9}{4}$

Answer: $x=-\frac{9}{4}$

galben [10]

Answer:

RS 14400

Step-by-step explanation:

Given the following :

Principal sum = RS 40000

Rate = 2 paisa per 2 rupee per month

Interest at the end of 3 years

1 rupee = 100 paisa

2 Paisa per 2 rupee per month :

2/200 per month = 1 / 100 per month,

Hence rate = 0.01 = 1% monthly

Annual rate = 1% × 12 = 12 % = 0.12

Simple interest :

Principal × rate × time

40000 × 0.12 × 3

40000 × 0.36

= RS 14,400
