2(z-3)=1.2-x

Solution for 2(z-3)=1.2-x equation:

Simplifying
2(z + -3) = 1.2 + -1x

Reorder the terms:
2(-3 + z) = 1.2 + -1x
(-3 * 2 + z * 2) = 1.2 + -1x
(-6 + 2z) = 1.2 + -1x

Solving
-6 + 2z = 1.2 + -1x

Solving for variable 'z'.

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

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

Combine like terms: -6 + 6 = 0
0 + 2z = 1.2 + 6 + -1x
2z = 1.2 + 6 + -1x

Combine like terms: 1.2 + 6 = 7.2
2z = 7.2 + -1x

Divide each side by '2'.
z = 3.6 + -0.5x

Simplifying
z = 3.6 + -0.5x
