Answer:
Rule 3
Step-by-step explanation:
The values correspond to the equation y=3^x
Its C. Add 3 and 15 which gives you 18. Then move the variable (4x) to the left. Then combine like terms which are the x’s and you should get 3x. Then divide both sides by 3. (18/3 = 6)
Your subtracting 3x from 5x: 5x-3x
This is so you only have a variable on one side
