-3r-15r=-8-10

-18r=-18

18r=18

ans: r=1

-9(t-2)=4(t-15)

Step-by-step explanation:

  • 26-4s=9s
  • 26=9s+4s
  • 26=13s
  • s=26/13
  • s=2

  • -3r+10=15r-8
  • -3r-15r=-8-10
  • -18r=-18
  • r=-18/-18
  • r=1

  • -9(t-2)=4(t-15)
  • -9t+18=4t-60
  • -9t-4t=-60-18
  • -13t=-78
  • t=-78/-13
  • t=6
