s+(3+0.22)+(s-0.12)=4.6

Solution for s+(3+0.22)+(s-0.12)=4.6 equation:

Simplifying
s + (3 + 0.22) + (s + -0.12) = 4.6

Combine like terms: 3 + 0.22 = 3.22
s + (3.22) + (s + -0.12) = 4.6
s + 3.22 + (s + -0.12) = 4.6

Reorder the terms:
s + 3.22 + (-0.12 + s) = 4.6

Remove parenthesis around (-0.12 + s)
s + 3.22 + -0.12 + s = 4.6

Reorder the terms:
3.22 + -0.12 + s + s = 4.6

Combine like terms: 3.22 + -0.12 = 3.1
3.1 + s + s = 4.6

Combine like terms: s + s = 2s
3.1 + 2s = 4.6

Solving
3.1 + 2s = 4.6

Solving for variable 's'.

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

Add '-3.1' to each side of the equation.
3.1 + -3.1 + 2s = 4.6 + -3.1

Combine like terms: 3.1 + -3.1 = 0.0
0.0 + 2s = 4.6 + -3.1
2s = 4.6 + -3.1

Combine like terms: 4.6 + -3.1 = 1.5
2s = 1.5

Divide each side by '2'.
s = 0.75

Simplifying
s = 0.75
