Question

- 4 ( 2 - x ) = 12 by systematic method

Answer 1

-8+4x=12 ( as -4 X 2 = -8 ; -4 X -x = +4x )

4x=12+8 ( 8 to R.H.S. )

4x=20

x=20/4

x=5

Answer 2

Answer:

x = 5

Step-by-step explanation:

The first step is to open the Brackets as follows :

-8 + 4x = 12

In order to solve x from the left side we will add 8 on both sides as follows :

-8 + 4x + 8 = 12 + 8

4x = 20

To get the value of x we now divide both sides by 4 as follows :

x = 20/4

x = 5

The value of x is therefore 5.
