Solve algebraically for x

3( X+1) - 5 X = 12 - ( 6X - 7 )

1st step : Simplify both sides:

3X + 3 - 5X = 12 - 6X + 7

-2X + 3 = 19 - 6x

2nd step : Move variables to one side and Constants to other, and simplify both sides.

-2X +6X = 19 -3

4X = 16

3rd Step: Solve for variable , by dividing both sides by coefficient of the variable

X =4

This 3 steps must be followed to solve any linear equation of single variable.
