Question

If 1/2 is subtracted from a number and the difference is multiple by 4 .the result is 5 . what is the number

Answer 1

Answer:

$\frac{14}{8}$

Step-by-step explanation:

LET TAKE THE NO. BE X SO:-

$4(x - \frac{1}{2} ) = 5$

AFTER SOLVING BRACKETS IT BECOMES

$4x - \frac{4}{2} = 5$

NOW LCM OF 1 AND 2 IS 2

THEN EQUATION BECOMES

$\frac{4x \times 2}{1 \times 2} - \frac{4 \times 1}{2 \times 1} = 5$

$= > \frac{8x - 4}{2} = 5$

SHIFTING 2 TO R.H.S

WE GET:-

$8x - 4 = 5 \times 2 \\ 8x - 4 = 10$

SHIFTING (-4) TO R.H.S WE GET

$8x = 10 + 4 \\ 8x = 14$

SHIFTING 8 TO R.H.S WE GET:-

$x = \frac{14}{8}$

THE NO.=X=14/8

MEANS THE NO IS

$\frac{14}{8}$
