Answer:

Tm = 6 - Ts

Explanation:

  1. We are given an equation and the variables that go with each part of the equation.
  2. If the equation is RmTm + RsTs = 170...
  3. And Rm is 20, Rs is 30, and Tm is Ts + 1...
  4. Then we can plug those variables in and solve algebraically.
  5. Currently we have 20 • (Tm + 1) + 30 • Ts = 170
  6. Subtract 30 from both sides.
  7. Now we have 20 • (Tm + 1) • Ts = 140
  8. Distribute 20.
  9. Now we have 20Tm + 20 • Ts = 140
  10. Subtract 20 from both sides.
  11. Now we have 20Tm • Ts = 120
  12. Divide 20Tm by 20, then divide 120 by 20.
  13. Tm • Ts = 6.
  14. Subtract Ts from both sides.
  15. Tm = 6 - Ts.

If I am incorrect in my reasoning, please let me know so that I can plan better for my future answers. Have an amazing day.
