Question

B ^2 = −g+ 1/8ra
Solve for a.

Answer 1

a = 8b^2/r + 8g/r

Explanation:

b^2 = −g+ 1/8ra

Get rid of g by adding g to both sides:

b^2 + g = 1/8ra

Get rid of 1/8 by dividing both sides by 1/8 (essentially multiplying by 8 to both sides):

8(b^2 + g) = ra

8b^2 + 8g = ra

Get a alone by dividing both sides by r:

8b^2/r + 8g/r = a

a = 8b^2/r + 8g/r
