Question

Solve the formula Ax+By = C for A.

O A A+
+ By
O B. A=C-BY
x
O C. A = C+By
O D. A = C-BY
X

Answer 1

`A = (C - By)/(x)`

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

`(Ax)/(x) = (C - By)/(x)`

`A = (C - By)/(x)`
