Hi, 

-9(x-9)=2(2-x)-2

removing the parenthesis by applying the distributive principle

-9x + 81 = 4 - 2x - 2

***isolating the variable x on one side of the equaton 

by performing operations on both sides of the equation

81 = 7x +2    adding 9x to both sides

79 = 7x       subtracting 2 from both sides of the equation

79/7 = x      dividing both sides by 7
