s+(s-0.45)+2(s+45)=9.25

Solution for s+(s-0.45)+2(s+45)=9.25 equation:

Simplifying
s + (s + -0.45) + 2(s + 45) = 9.25

Reorder the terms:
s + (-0.45 + s) + 2(s + 45) = 9.25

Remove parenthesis around (-0.45 + s)
s + -0.45 + s + 2(s + 45) = 9.25

Reorder the terms:
s + -0.45 + s + 2(45 + s) = 9.25
s + -0.45 + s + (45 * 2 + s * 2) = 9.25
s + -0.45 + s + (90 + 2s) = 9.25

Reorder the terms:
-0.45 + 90 + s + s + 2s = 9.25

Combine like terms: -0.45 + 90 = 89.55
89.55 + s + s + 2s = 9.25

Combine like terms: s + s = 2s
89.55 + 2s + 2s = 9.25

Combine like terms: 2s + 2s = 4s
89.55 + 4s = 9.25

Solving
89.55 + 4s = 9.25

Solving for variable 's'.

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

Add '-89.55' to each side of the equation.
89.55 + -89.55 + 4s = 9.25 + -89.55

Combine like terms: 89.55 + -89.55 = 0.00
0.00 + 4s = 9.25 + -89.55
4s = 9.25 + -89.55

Combine like terms: 9.25 + -89.55 = -80.3
4s = -80.3

Divide each side by '4'.
s = -20.075

Simplifying
s = -20.075
