Question

Rearrange w=3(2a+b)-4 can u please make a the subject of the formulae

Answer 1

Answer:

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

Step-by-step explanation:

What is being done will be written in brackets on the right

w = 3(2a+b)-4                            

w + 4  = 3(2a+b)                         [4 is added on both sides of the equation]

w + 4 = 6a + 3b                          [the brackets on the right is expanded]

w + 4 - 3b = 6a                           [3b is subtracted on both sides of the equation]

w/6 + 4/6 - 3b/6 = a                   [both sides are divided by 6]

a = w/6 +2/3 - b/2

Answer 2

I'll try to do each individual step, hopefully that'll clear it up
 w= 3(2a+b)-4
w+4= 3(2a+b)
(w+4)/3 = 2a+ b
2a= ((w+4)/3) - b
a= (((w+4)/3) - b)/ 2
