Solve for the missing variable 12x+3=6x-15

x = - 3

Step-by-step explanation:

12x + 3 = 6x - 15

Step 1: Subtract 3 from both sides

12x + 3 - 3 = 6x - 15 - 3

Step 2: Simplify

12x = 6x - 18

Step 3: Subtract 6x from both sides

12x - 6x = 6x - 18 - 6x

Step 4: Simplify

6x = - 18

Step 5: Divide both sides by 6

6x/6 = - 18/6

6x/6 - -> x - 18/6 - -> - 3

Answer: X = - 3

Your answer will be - 3!
