Question

find the vaule of a in ax+by=c

Answer 1

Answer:

a=$\frac{c-by}{x}$

Step-by-step 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=$\frac{c-by}{x}$

Hope this helps and have a great day :D

Answer 2

Answer:

$a x + by = c \\ ax = c - by \\ \frac{ax}{x} = \frac{c - by}{x} \\ a = \frac{c - by}{x}$
