Question

Solve ax + by = c, for b

Answer 1

`b= (c-ax)/(y)`

Explanation:

We can solve the question by isolating the variable

Step 1: Subtract ax from both sides.

`ax+by=c\\\\ax+by-ax=c-ax\\\\by=-ax+c`

Step 2: Divide both sides by y.

`(by)/(y) = (-ax+c)/(y)\\\\\\b= (-ax+c)/(y)`

The answer is:

`b= (c-ax)/(y)`

Answer 2

b=c-ax/y

Explanation:

1) ax + by = c

-ax

2) by = c - ax

3) by/y = b and c - ax/y

4) b = c-ax/y
