Answer:
w=20.3

Reorder the terms:


4 = 0.25(-4.3 + w)


4 = (-4.3 * 0.25 + w * 0.25)


4 = (-1.075 + 0.25w)

Solving


4 = -1.075 + 0.25w

Solving for variable 'w'.

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

Add '-0.25w' to each side of the equation.


4 + -0.25w = -1.075 + 0.25w + -0.25w

Combine like terms: 0.25w + -0.25w = 0.00


4 + -0.25w = -1.075 + 0.00


4 + -0.25w = -1.075

Add '-4' to each side of the equation.


4 + -4 + -0.25w = -1.075 + -4

Combine like terms: 4 + -4 = 0


0 + -0.25w = -1.075 + -4


-0.25w = -1.075 + -4

Combine like terms: -1.075 + -4 = -5.075


-0.25w = -5.075

Divide each side by '-0.25'.


w = 20.3

4 = 0.25 (w - 4.3). Divide each side by 0.25

16 = w - 4.3. Add 4.3 to each side.

20.3 = w
