6.5f - 5=20
what is the value of f with the steps

Answer 1

Given,

Equation,

6.5f - 5 = 20.

To find,

The value of 'f'.

Solution,

We can simply solve this problem by following the below steps.

Here, the given equation is,

6.5f - 5 = 20

Firstly, we need to rearrange the equation, on rearranging, we get,

6.5f = 20 + 5

⇒ 6.5f = 25

Now, we should remove the decimal, or convert the given '6.5' on LHS, into a fraction. To do this, we can remove the decimal, and place a '10' in the denominator. That is,

$\frac{65}{10}f=25$

Now, simply cross-multiply, that is,

⇒ $f=\frac{25\times 10}{65}$

⇒ $f=\frac{250}{65}$

⇒ $f=\frac{50}{13}$

Or, approximately,

f = 3.85.

Therefore, for the given equation, the value of f will be 50/13 or approx. 3.85.
