Question

rearrange the formula to make a the subject in
w=3(2a+b)-4
a=........................................

Answer 1

Step-by-step explanation:

$w = 3(2a + b) - 4 \\ w + 4 =3(2a + b) \\ \frac{w + 4}{3} = 2a + b \\ \frac{w + 4}{3} - b = 2a \\ \frac{w + 4 - 3b}{3} = 2a \\ a = \frac{w + 4 - 3b}{6}$
