Question

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

Answer 1

Answer:

a = $\frac{w+4-3b}{6}$

Step-by-step explanation:

Given

w = 3(2a + b) - 4 ( add 4 to both sides )

w + 4 = 3(2a + b) ← distribute

w + 4 = 6a + 3b ( isolate the term in a by subtracting 3b from both sides )

w + 4 - 3b = 6a ( divide both sides by 6 )

a = $\frac{w+4-3b}{6}$

Answer 2

Answer:

a=((w/3)-b)/2

Step-by-step explanation:

w=3(2a+b)

Divide both sides by 3

w/3=2a+b

Subtract b from both sides

(w/3)-b=2a

Divide both sides by 2

((w/3)-b)/2=a

State your answer

a=((w/3)-b)/2
