1.1(z-1.5)=-1.1(z-1)

Solution for 1.1(z-1.5)=-1.1(z-1) equation:

Simplifying
1.1(z + -1.5) = -1.1(z + -1)

Reorder the terms:
1.1(-1.5 + z) = -1.1(z + -1)
(-1.5 * 1.1 + z * 1.1) = -1.1(z + -1)
(-1.65 + 1.1z) = -1.1(z + -1)

Reorder the terms:
-1.65 + 1.1z = -1.1(-1 + z)
-1.65 + 1.1z = (-1 * -1.1 + z * -1.1)
-1.65 + 1.1z = (1.1 + -1.1z)

Solving
-1.65 + 1.1z = 1.1 + -1.1z

Solving for variable 'z'.

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

Add '1.1z' to each side of the equation.
-1.65 + 1.1z + 1.1z = 1.1 + -1.1z + 1.1z

Combine like terms: 1.1z + 1.1z = 2.2z
-1.65 + 2.2z = 1.1 + -1.1z + 1.1z

Combine like terms: -1.1z + 1.1z = 0.0
-1.65 + 2.2z = 1.1 + 0.0
-1.65 + 2.2z = 1.1

Add '1.65' to each side of the equation.
-1.65 + 1.65 + 2.2z = 1.1 + 1.65

Combine like terms: -1.65 + 1.65 = 0.00
0.00 + 2.2z = 1.1 + 1.65
2.2z = 1.1 + 1.65

Combine like terms: 1.1 + 1.65 = 2.75
2.2z = 2.75

Divide each side by '2.2'.
z = 1.25

Simplifying
z = 1.25
