Question

Solve C = AB + D for B.

AC- D = B
C/A - D = B
C-D/A = B
C+D/A = B

Answer 1

Start with C = AB + D. Subtract D: AB = C − D. Divide by A (assuming A ≠ 0): B = (C − D)/A.

So the correct solution is B = (C − D)/A — none of the listed choices (which parse as AC − D, C/A − D, C − D/A, or C + D/A) match that.
