Question

(1) If 4 is added to five times a number, the result is 12 more than three times the
number. Find the number.​

Answer 1

Let, the number be 'x'.

4 + 5x = 12 + 3x

5x - 3x = 12 - 4

2x = 8

x = 8/2

x = 4

Therefore, the number is 4.

Answer 2

$\sf\underline{\underline{ANSWER:}}$

Let the number be 'x'.

$\Longrightarrow$ 5x + 4 = 12 + 3x

$\longrightarrow$ 5x - 3x = 12 - 4

$\longrightarrow$ 2x = 8

$\longrightarrow$ x = 8/2

$\boxed{x = 4}$
