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