Question

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

Answer 1

Answer:

given w= 3(2a + b) - 4

to make a as the subject means we have to rewrite the given equation as a = ( )

w= 6a + 3b - 4

by transposing w + 4 - 3b = 6a

dividing both sides by 6 we get

(w + 4 - 4b)/6 = a

or a = (w - 4b + 4)
