Answer:

Explanation:

Subtract 10x from 17x
10x and 17x are like terms. So, the coefficients of like terms can be added or subtracted.

Distribute 5 through the parentheses


Move 5x to left hand side ( L.H.S ) and change it's sign
Similarly , move 2 to right hand side ( R.H.S ) and change it's sign

Subtract 5x from 7x

Add the numbers : 20 and 2

Divide both sides by 2


--------------------------------------------------------------
Now, let's check whether the value of x is 11 or not.
Verification :
L.H.S = n

Plug the value of x and simplify




R.H.S =

plug the value of x and simplify



L.H.S = R.H.S
The value of x is 11 .

Rules for solving an equation :
- If an equation contains fractions , multiply each term by the LCM of denominators.
- Remove the brackets , if any.
- Collect the terms with the variable to the left hand side and constant terms to the right side by changing their signs ' + ' into ' - ' and ' - ' into ' + '
- Simplify and get the single term on each side.
- Divide each side by the coefficient of variable and then get the value of variable.
