Question

4=0.25(w−4.3) Solve for w.

Answer 1

Solving:
$4 = 0.25(w - 4.3)$
Delete the first parentheses by the distributive property, with the distributive property, we multiply the '0.25' first:
$4 = 0.25w - 1.075$
Now, put the numbers with letter (incognito) to the right and numbers without letter to the left, changing the signal when changing sides.
$- 0.25w = - 4 - 1.075$
$- 0.25w = - 5.075$
simplify by (-1)
$- 0.25w = - 5.075\:*(-1)$
$0.25w = 5.075$
$w = \frac{5.075}{0.25}$
$\boxed{\boxed{w = 20.3}}\end{array}}\qquad\quad\checkmark$
