Answer:
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
