Reorder the terms:
9 + -7 + 210t = 0

2 + 210t = 0
Solving
2 + 210t = 0

Move all terms containing t to the left, all other terms to the right.
Add '-2' to each side of the equation. 2 + -2 + 210t = 0 + -2
Combine like terms: 2 + -2 = 0 0 + 210t = 0 + -2 210t = 0 + -2
Combine like terms: 0 + -2 = -2
210t = -2

Divide each side by '210'.
