Question

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

Answer 1

The answer is a = w + 4 - 3b/2

Explanation:

w = 3(2a + b) - 4

add 4 both sides we get,

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

w + 4 = 3(2a + b)

w + 4 = 6a + 3b

Subtract 3b from both sides we get,

w + 4 - 3b = 6a + 3b - 3b

w + 4 - 3b = 2a

Now, Divide both sides by 2 we get,

w + 4 - 3b/2 = 2a/2

a = w + 4 - 3b/2

Thus, The answer is a = w + 4 - 3b/2
