Answer:

a=
(c-by)/(x)

Explanation:

To find a, we need to change the equation so a is the variable that is left by itself. So...

ax+by=c Get rid of anything else besides the x and its coefficient.

-by -by

ax=c-by Because a has to be completely isolated, get rid of its coefficient.

/x /x

a=
(c-by)/(x)

Hope this helps and have a great day :D

Answer:


a x + by = c \\ ax = c - by \\ (ax)/(x) = (c - by)/(x) \\ a = (c - by)/(x)
