Step-by-step explanation:

Step 1: Define

3t + 7 = 2 + 5t

Step 2: Solve for t

  1. [Subtraction Property of Equality] Isolate t terms:                                        7 = 2 + 2t
  2. [Subtraction Property of Equality] Isolate t term:                                         5 = 2t
  3. [Division Property of Equality] Isolate t:                                                        5/2 = t
  4. Rewrite:                                                                                                             t = 5/2

Answer:

t = ⁵⁄₂ or 2.5

Explanation:

3t + 7 = 2 + 5t

  • Simplify both sides of the equation

3t + 7 = 5t + 2

  • Subtract 5t from both sides

3t + 7 − 5t = 5t + 2 − 5t

−2t + 7 = 2

  • Subtract 7 from both sides

−2t + 7 − 7 = 2 − 7

−2t = −5

Divide both sides by -2

−2t / -2 = −5 / -2

  • Simplify

t = ⁵⁄₂

  • Turn the fraction into a decimal

t = 2.5

t = ⁵⁄₂ or 2.5
