Solution for 1-0.4(z-10)=0.8(12z-10) equation:


Simplifying
1 + -0.4(z + -10) = 0.8(12z + -10)

Reorder the terms:
1 + -0.4(-10 + z) = 0.8(12z + -10)
1 + (-10 * -0.4 + z * -0.4) = 0.8(12z + -10)
1 + (4 + -0.4z) = 0.8(12z + -10)

Combine like terms: 1 + 4 = 5
5 + -0.4z = 0.8(12z + -10)

Reorder the terms:
5 + -0.4z = 0.8(-10 + 12z)
5 + -0.4z = (-10 * 0.8 + 12z * 0.8)
5 + -0.4z = (-8 + 9.6z)

Solving
5 + -0.4z = -8 + 9.6z

Solving for variable 'z'.

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

Add '-9.6z' to each side of the equation.
5 + -0.4z + -9.6z = -8 + 9.6z + -9.6z

Combine like terms: -0.4z + -9.6z = -10z
5 + -10z = -8 + 9.6z + -9.6z

Combine like terms: 9.6z + -9.6z = 0.0
5 + -10z = -8 + 0.0
5 + -10z = -8

Add '-5' to each side of the equation.
5 + -5 + -10z = -8 + -5

Combine like terms: 5 + -5 = 0
0 + -10z = -8 + -5
-10z = -8 + -5

Combine like terms: -8 + -5 = -13
-10z = -13

Divide each side by '-10'.
z = 1.3

Simplifying
z = 1.3
