Answer:
If [tex]\frac{1}{2}[/tex] is subtracted by a no. and the difference is multiplied by 4 the result is 5 number is [tex]\frac{-3}{4}[/tex]
Solution:
Let’s assume the required number is x.
Given that [tex]\frac{1}{2}[/tex] is subtracted by “x”
On subtracting [tex]\frac{1}{2}[/tex] by given number we get ([tex]\frac{1}{2}[/tex]) – x
Given that the difference is multiplied by 4
Now multiply the above difference by four,
4 ( ([tex]\frac{1}{2}[/tex]) – x )
On simplification, we get
= 2 – 4x
Given that above expression is equal to 5.
So 2 – 4x = 5
-4x = 5 – 2 = 3
x = [tex]\frac{-3}{4}[/tex]
Hence required number is [tex]\frac{-3}{4}[/tex]
