Question

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

Answer 1

a =
`(w + 4 - 3b)/(6)`

Explanation:

Given

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

w + 4 = 3(2a + b) ← distribute parenthesis

w + 4 = 6a + 3b ( subtract 3b from both sides )

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

`(w+4-3b)/(6)` = a
