Answer:

x = 2.5

Step-by-step explanation:

  • Expand the brackets
  • [tex]27+9x=12+3x[/tex]
  • Subtract 3x from both sides
  • [tex]27+6x=12[/tex]
  • Subtract 27 from both sides
  • [tex]6x=-15[/tex]
  • Divide both sides by 6
  • [tex]x=2.5[/tex]

Answer:

x = -3

Step-by-step explanation:

9(3+x) = 4(3+x)

9(3+x) - 4(3+x) = 0

(9-4)(3+x) = 0

5(3+x) = 0

15+5x = 0

-15 = 5x

x = -3
