Answer :

dingo
5x- 12=2x- 6
5x- 2x = -6+12
3x=6
x=6/3
x=2

answer : 2

explanation : 5x - 12 = 2x - 6

add 6 to both sides so you remove the constant term on the right side.

i.e., 5x - 12 + 6 = 2x - 6 + 6

or, 5x - 6 = 2x

subtract (2x) from both sides so you remove the variable term from right hand side.

i.e., 5x - 6 - 2x = 2x - 2x

or, 5x - 2x - 6 = 0

or, 3x - 6 = 0

add 6 to both sides so you remove the constant term on the left hand side.

i.e., 3x - 6 + 6 = 6

or, 3x = 6

divide both sides by 3

or, 3x/3 = 6/3

or, x = 2

hence, value of x = 2
