0.2z+4(0.3+0.2z)=2.2

Solution for 0.2z+4(0.3+0.2z)=2.2 equation:

Simplifying
0.2z + 4(0.3 + 0.2z) = 2.2
0.2z + (0.3 * 4 + 0.2z * 4) = 2.2
0.2z + (1.2 + 0.8z) = 2.2

Reorder the terms:
1.2 + 0.2z + 0.8z = 2.2

Combine like terms: 0.2z + 0.8z = 1z
1.2 + 1z = 2.2

Solving
1.2 + 1z = 2.2

Solving for variable 'z'.

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

Add '-1.2' to each side of the equation.
1.2 + -1.2 + 1z = 2.2 + -1.2

Combine like terms: 1.2 + -1.2 = 0.0
0.0 + 1z = 2.2 + -1.2
1z = 2.2 + -1.2

Combine like terms: 2.2 + -1.2 = 1
1z = 1

Divide each side by '1'.
z = 1

Simplifying
z = 1
