5(t + 7) = 2(2t + 7)

 Reorder the terms:
5(7 + t) = 2(2t + 7)
(7 5 + t 5) = 2(2t + 7)
(35 + 5t) = 2(2t + 7)
  Reorder the terms:
35 + 5t = 2(7 + 2t)
35 + 5t = (7 2 + 2t 2)
35 + 5t = (14 + 4t)

 Solving
35 + 5t = 14 + 4t

 Solving for variable 't'.

 Move all terms containing t to the left, all other terms to the right.

 Add '-4t' to each side of the equation.
 35 + 5t + -4t = 14 + 4t + -4t
  Combine like terms: 5t + -4t = 1t
35 + 1t = 14 + 4t + -4t

 Combine like terms: 4t + -4t = 0
35 + 1t = 14 + 0
35 + 1t = 14

 Add '-35' to each side of the equation.
35 + -35 + 1t = 14 + -35

 Combine like terms: 35 + -35 = 0
0 + 1t = 14 + -35
1t = 14 + -35

 Combine like terms: 14 + -35 = -21
1t = -21
  Divide each side by '1'.
t = -21
  Simplifying
t = -21
