Answer:

  • n = 1
  • x = 65

Step-by-step explanation:

Given

  • 18n + 12 = 27n + 3
  • 5(x + 7) = 6(x - 5)

Solving for variables

1

  • 18n + 12 = 27n + 3
  • 18n - 27n = 3 - 12
  • -9n = -9
  • n = -9/-9
  • n = 1

2

  • 5(x + 7) = 6(x - 5)
  • 5x + 35 = 6x - 30
  • 5x - 6x = -30 - 35
  • -x = -65
  • x = 65

Answer:

18n + 12 = 27n + 3

12-3=27n-18n

9=9n

n=9/9=1

5(x + 7) = 6(x - 5)

5x+35=6x-30

35+30=6x-5x

65=x

:.x=65
