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
Answer: [tex]w=20.3[/tex]
Reorder the terms:
[tex]4 = 0.25(-4.3 + w)[/tex]
[tex]4 = (-4.3 * 0.25 + w * 0.25)[/tex]
[tex]4 = (-1.075 + 0.25w)[/tex]
Solving
[tex]4 = -1.075 + 0.25w[/tex]
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.
[tex]4 + -0.25w = -1.075 + 0.25w + -0.25w[/tex]
Combine like terms: 0.25w + -0.25w = 0.00
[tex]4 + -0.25w = -1.075 + 0.00[/tex]
[tex]4 + -0.25w = -1.075[/tex]
Add '-4' to each side of the equation.
[tex]4 + -4 + -0.25w = -1.075 + -4[/tex]
Combine like terms: 4 + -4 = 0
[tex]0 + -0.25w = -1.075 + -4[/tex]
[tex]-0.25w = -1.075 + -4[/tex]
Combine like terms: -1.075 + -4 = -5.075
[tex]-0.25w = -5.075[/tex]
Divide each side by '-0.25'.
[tex]w = 20.3[/tex]
