Rerange w= 3(2a+b)-4 to make a the subject

To solve for a:

w = 3(2a + b) - 4     Given
w = 6a + 3b - 4        Apply the distributive property
w - 6a = 3b - 4         Subtract 6a from both sides
-6a = 3b - 4 - w        Subtract w from both sides
a = -3b - 4 - w / 6     Divide both sides by -6

a = -3b - 4 - w / 6

Hope this helps!

Ithink is a. true, but not sure
