Question

Amina thinks of a number and subtracts 5/4 from it.she multiplies the result by 16. The result now obtained is 6 times the same number she thought of. What is the number. *​

Answer 1

Answer:

2

Step-by-step explanation:

Let the no. =x

result of

$x - \frac{5}{4} = \frac{(4x - 5)}{4} \times 16 = (4x - 5) \times 4 \\ 16x - 20$

so the result is 6 times the same no. which means

.

$6x = 16x - 20$

so now solve this equation

$6x = 16x - 20 \\ 6x - 16x = - 20 \\ - 10x = - 20 \\ x = \frac{ - 20}{ - 10} \: \: \: - and \: - \: cancel \: out \\ x = 2$
