Solution for 2.7(z-1)=0.5(z-12) equation:


Simplifying
2.7(z + -1) = 0.5(z + -12)

Reorder the terms:
2.7(-1 + z) = 0.5(z + -12)
(-1 * 2.7 + z * 2.7) = 0.5(z + -12)
(-2.7 + 2.7z) = 0.5(z + -12)

Reorder the terms:
-2.7 + 2.7z = 0.5(-12 + z)
-2.7 + 2.7z = (-12 * 0.5 + z * 0.5)
-2.7 + 2.7z = (-6 + 0.5z)

Solving
-2.7 + 2.7z = -6 + 0.5z

Solving for variable 'z'.

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

Add '-0.5z' to each side of the equation.
-2.7 + 2.7z + -0.5z = -6 + 0.5z + -0.5z

Combine like terms: 2.7z + -0.5z = 2.2z
-2.7 + 2.2z = -6 + 0.5z + -0.5z

Combine like terms: 0.5z + -0.5z = 0.0
-2.7 + 2.2z = -6 + 0.0
-2.7 + 2.2z = -6

Add '2.7' to each side of the equation.
-2.7 + 2.7 + 2.2z = -6 + 2.7

Combine like terms: -2.7 + 2.7 = 0.0
0.0 + 2.2z = -6 + 2.7
2.2z = -6 + 2.7

Combine like terms: -6 + 2.7 = -3.3
2.2z = -3.3
