Question

can some one help with this formula. I need to solve for b
w=4/5(xb+m)

Answer 1

\[ w = \frac{4}{5} \left( xb +m\right) \]
the first step could be: multiply both sides by 5/4
what do you get ?

Answer 2

5/4w=xb+m

Answer 3

next add - m to both sides

Answer 4

(but I would write it (5/4) w = xb+ m because 5/4w looks like \(\frac{5}{4w}\)

Answer 5

or maybe
5w/4 = xb+m

is clearer.

Answer 6

next step is add - m to both sides
52/4 - m = xb + m - m

Answer 7

next step is add - m to both sides
5w/4 - m = xb + m - m
