Answer:

x = -3

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

Answer:

x = 2.5

Explanation:

  • Expand the brackets

  • 27+9x=12+3x
  • Subtract 3x from both sides

  • 27+6x=12
  • Subtract 27 from both sides

  • 6x=-15
  • Divide both sides by 6

  • x=2.5
