2.2+0.3z=3-0.5z-0.8z

Solution for 2.2+0.3z=3-0.5z-0.8z equation:

Simplifying
2.2 + 0.3z = 3 + -0.5z + -0.8z

Combine like terms: -0.5z + -0.8z = -1.3z
2.2 + 0.3z = 3 + -1.3z

Solving
2.2 + 0.3z = 3 + -1.3z

Solving for variable 'z'.

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

Add '1.3z' to each side of the equation.
2.2 + 0.3z + 1.3z = 3 + -1.3z + 1.3z

Combine like terms: 0.3z + 1.3z = 1.6z
2.2 + 1.6z = 3 + -1.3z + 1.3z

Combine like terms: -1.3z + 1.3z = 0.0
2.2 + 1.6z = 3 + 0.0
2.2 + 1.6z = 3

Add '-2.2' to each side of the equation.
2.2 + -2.2 + 1.6z = 3 + -2.2

Combine like terms: 2.2 + -2.2 = 0.0
0.0 + 1.6z = 3 + -2.2
1.6z = 3 + -2.2

Combine like terms: 3 + -2.2 = 0.8
1.6z = 0.8

Divide each side by '1.6'.
z = 0.5

Simplifying
z = 0.5
