Which equation is equal to y = ax - b, but has been rearranged to be solved for x?

Question

A. X= (y-a)/b

B. X= (y+b)/a

B. X= (y-b)/a

C. X= (y+a)/b

(Read the Title to understand this selection.)

Answer 1

Start with y = ax - b

rearrange to make x subject

so y = ax - b ≡ y + b = ax ≡ x = ^{(y + b)} / _a

which is answer B
