Question

If BA + C = D, solve for A

Answer 1

BA + C = D

Subtract C on both sides

BA + C - C = D - C

BA = D - C

Divide B on both sides


`(BA)/(B) =(D-C)/(B)\\\\\ \boxed{\bf{A =(D-C)/(B)}}`

Answer 2

To solve for A, we just have to isolate A on one side of the equation, like this:


`BA+C=D \\ (BA+C)-C=(D)-C \\ BA=D-C \\ (BA)/B=(D-C)/B \\ A= (D-C)/(B)`

The answer is A=(D-C)/B.

Hope this helps!
