3 + 10t = (1 * -3 + -3t * -3)
3 + 10t = (-3 + 9t)

Solving
3 + 10t = -3 + 9t

Solving for variable 't'.

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

Add '-9t' to each side of the equation.
3 + 10t + -9t = -3 + 9t + -9t

Combine like terms: 10t + -9t = 1t
3 + 1t = -3 + 9t + -9t

Combine like terms: 9t + -9t = 0
3 + 1t = -3 + 0
3 + 1t = -3

Add '-3' to each side of the equation.
3 + -3 + 1t = -3 + -3

Combine like terms: 3 + -3 = 0
0 + 1t = -3 + -3
1t = -3 + -3

Combine like terms: -3 + -3 = -6
1t = -6

Divide each side by '1'.
t = -6

Simplifying
t = -6
