Simplifying
-1(t + 7) + -1(2 + -1t) = 3(t + 5) + -5(4 + -1t)

Reorder the terms:
-1(7 + t) + -1(2 + -1t) = 3(t + 5) + -5(4 + -1t)
(7 * -1 + t * -1) + -1(2 + -1t) = 3(t + 5) + -5(4 + -1t)
(-7 + -1t) + -1(2 + -1t) = 3(t + 5) + -5(4 + -1t)
-7 + -1t + (2 * -1 + -1t * -1) = 3(t + 5) + -5(4 + -1t)
-7 + -1t + (-2 + 1t) = 3(t + 5) + -5(4 + -1t)

Reorder the terms:
-7 + -2 + -1t + 1t = 3(t + 5) + -5(4 + -1t)

Combine like terms: -7 + -2 = -9
-9 + -1t + 1t = 3(t + 5) + -5(4 + -1t)

Combine like terms: -1t + 1t = 0
-9 + 0 = 3(t + 5) + -5(4 + -1t)
-9 = 3(t + 5) + -5(4 + -1t)

Reorder the terms:
-9 = 3(5 + t) + -5(4 + -1t)
-9 = (5 * 3 + t * 3) + -5(4 + -1t)
-9 = (15 + 3t) + -5(4 + -1t)
-9 = 15 + 3t + (4 * -5 + -1t * -5)
-9 = 15 + 3t + (-20 + 5t)

Reorder the terms:
-9 = 15 + -20 + 3t + 5t

Combine like terms: 15 + -20 = -5
