Answer 2

Answer:

We will get the value of x$=1.25$

Step-by-step explanation:

In accordance with the information provided in the question,

Given the data in question 7x-2=8-x

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 to another side  

So, we will shift 2 from LHS to RHS the sign will change from  negative to positive,

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

As we get,

$7x-2=8-x\\7x+x=8+2\\8x=10$

Dividing both side by $8$ we get,

$\frac{8x}{8} =\frac{10}{8} \\x=\frac{5}{4} \\x=1.25$

So, check the balance equation when putting the value of x=$1.25$ in the equation,

$7x-2=8-x\\7\times 1.25-2=8- 1.25\\8.75-2=6.75\\6.75=6.75$

Hence proved LHS=RHS

Hence we will get the value of x$=1.25$
