Hi

My recommendation for linear equations is to 'focus' on isolating the

variable on one side of the equation and take the steps that are allowable

to accomplish that.  



For example: Doing allowable steps is for the 'sole purpose' of isolating x

2(x+5) - 4 = 5x + 6(x-1)  |remove parenthsis by applying distributive principle

 2x + 10 - 4 = 5x + 6x - 6  |combining like terms on both sides

 2x + 6 = 11x - 6    |adding 6 to both sides of equation to combine like terms

  2x + 12 = 11x       |subtracting 2x from both sides to combine like terms

      12 = 9x         |dividing both sides of equation by 9 to finish!

      12/9 = x

 OR x = 1 1/3
