Answer :
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
