Answer:

t =
(3)/(2)

Explanation:

Given

(6t - 9) + 8 = 7 + 2(t - 1) ← distribute parenthesis on both sides

6t - 9 + 8 = 7 + 2t - 2 , that is

6t - 1 = 5 + 2t ( subtract 2t from both sides )

4t - 1 = 5 ( add 1 to both sides )

4t = 6 ( divide both sides by 4 )

t =
(6)/(4) =
(3)/(2)

\large \mathfrak{Solution : }

let's solve for t :

  • 6t - 9 + 8 = 7 + 2(t - 1)

  • 6t - 1 = 7 + 2t - 2

  • 6t - 2t = 5 + 1

  • 4t = 6

  • t = 6 ÷ 4

  • t = 3/2 or 1.5
