Answer:

x>3

Step-by-step explanation:

  • First distribute the 3 to the inside of the parentheses:
  • [tex]3 \times x = 3x \\ 3 \times 4 = 12[/tex]
  • you should then get 3x+12>21
  • next you want to subtract over 12 from both sides:
  • [tex]3x + 12 > 21\ \\ 3x > 9[/tex]
  • then divide 3 over on both sides
  • [tex]3x > 9 \\ 9 \div 3 = 3 \\ x > 3[/tex]
  • you should then get x>3 for your final answer
