❤ Saiyyan ❤

Just separate out the like terms and solve,

1- 4x - 2 = 1 - x +1

3x = - 3

x = - 1

Answer 2

Answer:

x = - 1

Step-by-step explanation:

We are given an equation and we have to find the value of the unknown variable .

Here x is the unknown variable to be found.

1 - 2 ( 2 x + 1 ) = 1 - ( x - 1 )

We have to open the brackets first and then we will proceed .

⇒ 1 - 4 x - 2 = 1 - x + 1

Ф Note that ( - 2 ) was multiplied and ( - 1 ) was multiplied in order to open the brackets .

⇒ 1 - 4 x - 2 = 1 - x + 1

Now we will group the like terms :

⇒ 1 - 2 - 4 x = 1 + 1 - x

Now we will add the terms :

⇒ - 4 x - 1 = 2 - x

Try to transpose the values so as to keep the variable on the left hand side and numbers on the right :

⇒ - 4 x + x = 2 + 1

⇒ - 3 x = 3

⇒ x = 3 / - 3

⇒ x = - 1
