Answer 2

In the given equation $0.5X-2.5=77.5-0.3X$, the value of X  is 100.

Given,

The equation: $0.5X-2.5=77.5-0.3X$.

To Find,

The value of X.

Solution,

The method of finding the value of X is as follows -

We need to simplify the equation.

$0.5X-2.5=77.5-0.3X$

⇒ $0.5X+0.3X=77.5+2.5$ [ Adding 0.3X and 2.5 to both the side of the equation ]

⇒ $0.8X=80$

⇒ $X=\frac{80}{0.8} =\frac{800}{8}$

⇒ $X=100$.

Hence, in the given equation $0.5X-2.5=77.5-0.3X$, the value of X  is 100.
