Solution for 3-0.5(w-3)=0.3(w-8) equation: 


Simplifying
3 + -0.5(w + -3) = 0.3(w + -8)

Reorder the terms:
3 + -0.5(-3 + w) = 0.3(w + -8)
3 + (-3 * -0.5 + w * -0.5) = 0.3(w + -8)
3 + (1.5 + -0.5w) = 0.3(w + -8)

Combine like terms: 3 + 1.5 = 4.5
4.5 + -0.5w = 0.3(w + -8)

Reorder the terms:
4.5 + -0.5w = 0.3(-8 + w)
4.5 + -0.5w = (-8 * 0.3 + w * 0.3)
4.5 + -0.5w = (-2.4 + 0.3w)

Solving
4.5 + -0.5w = -2.4 + 0.3w

Solving for variable 'w'.

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

Add '-0.3w' to each side of the equation.
4.5 + -0.5w + -0.3w = -2.4 + 0.3w + -0.3w

Combine like terms: -0.5w + -0.3w = -0.8w
4.5 + -0.8w = -2.4 + 0.3w + -0.3w

Combine like terms: 0.3w + -0.3w = 0.0
4.5 + -0.8w = -2.4 + 0.0
4.5 + -0.8w = -2.4

Add '-4.5' to each side of the equation.
4.5 + -4.5 + -0.8w = -2.4 + -4.5

Combine like terms: 4.5 + -4.5 = 0.0
0.0 + -0.8w = -2.4 + -4.5
-0.8w = -2.4 + -4.5

Combine like terms: -2.4 + -4.5 = -6.9
-0.8w = -6.9

Divide each side by '-0.8'.
w = 8.625

Simplifying
w = 8.625
