99 points! explained answers . will give brainliest to best(and correct)answer simplify using distributive property, combining like terms then solve. 3(x − 1) − 2x = 9

x = 12

Step-by-step explanation:

3(x - 1) - 2x = 9             remove the brackets using the distributive property

3x - 3 - 2x = 9              Collect 3x and -2x (Collect  like terms)

3x - 2x - 3 = 9              Use the reverse of the distributive property to get x

x(3 - 2) - 3 = 9              Do what is inside the brackets

x - 3 = 9                        Add 3 to both sides (additive inverse)

x - 3 + 3 = 9+3             Combine like terms on the left

x = 12
