2[y-3]=1.2-y

Solution for 2[y-3]=1.2-y equation:

Simplifying
2[y + -3] = 1.2 + -1y

Reorder the terms:
2[-3 + y] = 1.2 + -1y
[-3 * 2 + y * 2] = 1.2 + -1y
[-6 + 2y] = 1.2 + -1y

Solving
-6 + 2y = 1.2 + -1y

Solving for variable 'y'.

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

Add 'y' to each side of the equation.
-6 + 2y + y = 1.2 + -1y + y

Combine like terms: 2y + y = 3y
-6 + 3y = 1.2 + -1y + y

Combine like terms: -1y + y = 0
-6 + 3y = 1.2 + 0
-6 + 3y = 1.2

Add '6' to each side of the equation.
-6 + 6 + 3y = 1.2 + 6

Combine like terms: -6 + 6 = 0
0 + 3y = 1.2 + 6
3y = 1.2 + 6

Combine like terms: 1.2 + 6 = 7.2
3y = 7.2

Divide each side by '3'.
y = 2.4

Simplifying
y = 2.4
