12-3(7-2t)=3(t-1)

Solution for 12-3(7-2t)=3(t-1) equation:

Simplifying
12 + -3(7 + -2t) = 3(t + -1)
12 + (7 * -3 + -2t * -3) = 3(t + -1)
12 + (-21 + 6t) = 3(t + -1)

Combine like terms: 12 + -21 = -9
-9 + 6t = 3(t + -1)

Reorder the terms:
-9 + 6t = 3(-1 + t)
-9 + 6t = (-1 * 3 + t * 3)

-9 + 6t = -3 + 3t

Solving for variable 't'.

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

Add '-3t' to each side of the equation.
-9 + 6t + -3t = -3 + 3t + -3t

Combine like terms: 6t + -3t = 3t
-9 + 3t = -3 + 3t + -3t

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

Add '9' to each side of the equation.
