Question

Solve the equation for the indicated variable. Ax+By=​C; y

Answer 1

y =
`(C-Ax)/(B)`

Explanation:

Ax + By = C ( subtract Ax from both sides )

By = C - Ax ( divide both sides by B )

y =
`(C-Ax)/(B)` (B ≠ 0 )

Answer 2

y = (C-Ax)/B

Explanation:

We first move Ax to the right by subtracting from both sides

Ax+By=C

Ax+By - Ax = C - Ax

By = C - Ax

Now we divide by B

y = (C - Ax)/B

note that it only works if B ≠ 0
