Solve the formula Ax+By = C for A.

jok3333 [9.3K]

Answer:

$A = \frac{C - By}{x}$

Step-by-step explanation:

Given

$Ax + By = C$

Required

Solve for A

The question implies that we make A the subject of the formula.

Start by subtracting By from both sides of the equation by x

$Ax + By - By= C - By$

$Ax = C - By$

Divide both sides by x

$\frac{Ax}{x} = \frac{C - By}{x}$

$A = \frac{C - By}{x}$
