Question

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

Answer 1

w = 3(2a + b) - 4

First, add 4 to both sides:

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

w + 4 = 3(2a + b)

Next, divide 3 from both sides:

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

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

Next, subtract b from both sides:

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

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

Finally, divide 2 from both sides:

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

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

a = (((w + 4)/3) - b)/2 is your answer.

Answer 2

Answer:

$\frac{w}{6} +\frac{2}{3} -\frac{3b}{6}$=a

Step-by-step explanation:

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

w+4=3(2a+b) --> distribute the 3

w+4= 6a+3b--> subtract 3b from both sides

w+4-3b=6a ---> to isolate the a divide both sides by 6

$\frac{w}{6} +\frac{2}{3} -\frac{3b}{6}$= a ---> I hope this was what you were looking for
