how do you rearrange ab-ex=e to make b the subject of the formlar and ab-ex=e to make e the subject?

Answer 1

1.ab-ex=e
ab=e+ex
b=a/(e+ex)

2. ab-ex=e
e+ex=ab
e(1+x)=ab
e=ab/(1+x)

Answer 2

ab - ex = e
ab = e + ex
divide both sides by a : b =e + ex / a

Answer 3

Question 1
ab = e + ex = e(1 + x)
b = e(1 + x) / a

Question 2
ab = e + ex
ab = e(1 + x)
e = ab / (1 + x)

Answer 4

1.send -ex to the left hand side ab=e + ex....then send b to the left hand side
therefore------------ a=(e+ex)/b

2. firstly take e to the right hand side and ab to the left hand side
-ex-e= -ab......then multiply this equation by -1 to give ex+e=ab..
factorise the right hand side e(x+1)=ab and send (x+1) to the left hand side i.e. e=ab/(x+1)

Answer 5

ab - ex = e
ab = e + ex
b = (e + ex)/a



ab - ex = e
ab = e + ex
ab = e(1 + x)
ab/(1+x) = e
