Answer:

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

Answer:

x=12

Step-by-step explanation:

3(x−1)−2x=9

(3)(x)+(3)(−1)+−2x=9         we are going to distribute it

3x+−3+−2x=9

(3x+−2x)+(−3)=9            and then combine the terms

x+−3=9

x−3=9

x−3+3=9+3

x=12
