Question

Make b the subject of the formula a = vb + 6​

Answer 1

`b = (a -6)/(v)`

Explanation:

Given

`a = vb + 6`

Required

Make b the subject

`a = vb + 6`

Subtract 6 from both sides

`a -6= vb + 6-6`

`a -6= vb`

Divide both sides by v

`(a -6)/(v)= (vb)/(v)`

`(a -6)/(v)= b`

Reorder

`b = (a -6)/(v)`
