Answer 2

Answer:

The required value of x$=4.5$

Step-by-step explanation:

In accordance with the information provided in the question,

Given the data in question 20x-10 =80

We have find the value of" x" in the above question.

Here we will use the transposition method.

Hence, for solving the above equation, we will solve it by separating the like terms at one side  ,

So, we will shift 10 from LHS to RHS the sign will change from negative to positive,

As we get,

$20x-10=80\\20x=80+10\\20x=90$

Dividing both side by 20 we get,

$\frac{20x}{20} =\frac{90}{20}$

Simplifying further we get,

$x=\frac{9}{2} \\x=4.5$

Hence the required value of x$=4.5$
