12-2(9-2t)=2(t-1)

Solution for 12-2(9-2t)=2(t-1) equation:

Simplifying
12 + -2(9 + -2t) = 2(t + -1)
12 + (9 * -2 + -2t * -2) = 2(t + -1)
12 + (-18 + 4t) = 2(t + -1)

Combine like terms: 12 + -18 = -6
-6 + 4t = 2(t + -1)

-6 + 4t = -2 + 2t

Solving for variable 't'.

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

Add '-2t' to each side of the equation.
-6 + 4t + -2t = -2 + 2t + -2t

Combine like terms: 4t + -2t = 2t
-6 + 2t = -2 + 2t + -2t

Combine like terms: 2t + -2t = 0
-6 + 2t = -2 + 0
-6 + 2t = -2

Add '6' to each side of the equation.
-6 + 6 + 2t = -2 + 6

Combine like terms: -6 + 6 = 0
0 + 2t = -2 + 6
2t = -2 + 6

Combine like terms: -2 + 6 = 4
2t = 4

Divide each side by '2'.
t = 2
