​

Answer 1

Answer:]

original number = $\frac{-1}{8}$

Step-by-step explanation:

( 5- 4x )  x  2  = 6

5 - 4x  x  2 = 6

-4x = 6 - 5 /2

-4x = 1/2

x = 1/2 x -1/4

x = $\frac{-1}{8}$

Answer 2

Answer:

The original Number is 2

Step-by-step explanation:

we know that,

2(4x-5) = 6 (According to Question)

Now we can do the math in two ways.

1st method :

Multiply 2 by (4x-5)

=> 8x-10 = 6

=> 8x = 6+10

=> 8x = 16

=> x = 16/8

=> x = 2

2nd Method :

• 2(4x-5) = 6
• 4x-5 = 6/2 (move the 2 from the left side to the right side)
• 4x-5 = 3
• 4x = 3+5
• 4x = 8
• x = 8/4
• x = 2
