$5x - 7 = x + 5$
​

Answer 1

Answer:

⠀

$\huge\fbox\red{❥AnsWer:}$

➡️ 5x - 7 = x + 5

➡️ 5x - x = 5 + 7

➡️ 4x = 12

➡️ x = 12/4

➡️ x = 3

hope it helps you

Answer 2

Answer :-

$\sf \: 5x - 7 = x + 5$

$\sf5x - x = 5 + 7$

$\sf4x = 12$

$\sf \: x = \frac{12}{4}$

$\sf \: x = 3.$

Thus, x = 3.

Verification :-

To check whether our answer is correct or not, all we have to do is put 3 in place of x and see if the LHS = RHS.

Lets do it!

Putting 3 in place of x, we get :-

$\sf5 \times 3 - 7 = 3 + 5$

$\sf15 - 7 = 8$

$\sf8 = 8.$

$\sf \: Since \: LHS = RHS,$

$\sf \: Hence \: verified.$

Thus, x = 3 and our answer is correct!

How to solve Linear Equations with one variable?

To solve Linear Equations with one variable, you have to bring all the numbers in one side and the variable (x, y etc) in the other side. While transposing (transferring) the numbers from one side to another, the signs will change.

For example :- (+) will become (-) and (×) will become (÷)
