s+(3s+0.02)+(s-0.12)=4.6

Solution for s+(3s+0.02)+(s-0.12)=4.6 equation:

Simplifying
s + (3s + 0.02) + (s + -0.12) = 4.6

Reorder the terms:
s + (0.02 + 3s) + (s + -0.12) = 4.6

Remove parenthesis around (0.02 + 3s)
s + 0.02 + 3s + (s + -0.12) = 4.6

Reorder the terms:
s + 0.02 + 3s + (-0.12 + s) = 4.6

Remove parenthesis around (-0.12 + s)
s + 0.02 + 3s + -0.12 + s = 4.6

Reorder the terms:
0.02 + -0.12 + s + 3s + s = 4.6

Combine like terms: 0.02 + -0.12 = -0.1
-0.1 + s + 3s + s = 4.6

Combine like terms: s + 3s = 4s
-0.1 + 4s + s = 4.6

Combine like terms: 4s + s = 5s
-0.1 + 5s = 4.6

Solving
-0.1 + 5s = 4.6

Solving for variable 's'.

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

Add '0.1' to each side of the equation.
-0.1 + 0.1 + 5s = 4.6 + 0.1

Combine like terms: -0.1 + 0.1 = 0.0
0.0 + 5s = 4.6 + 0.1
5s = 4.6 + 0.1

Combine like terms: 4.6 + 0.1 = 4.7
5s = 4.7

Divide each side by '5'.
s = 0.94

Simplifying
s = 0.94
