how do you solve 3(x+1) - 5x = 12 - (6x -7)

Question

Solve algebraically for x

Answer 1

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.
