Express the following linear equations in the form ax + by + c = 0 and indicate the values of a, b and c in each case:
(i) 2x + 3y = \(9.3 \bar 5\)
(ii) x –(y/5)–10 = 0

(i) 2x + 3y = \(9.3 \bar 5\)
Re-arranging the equation, we get,
2x + 3y - \(9.3 \bar 5\) = 0
The equation 2x + 3y - \(9.3 \bar 5\) = 0 can be written as,
2x + 3y - \(9.3 \bar 5\) = 0
Now comparing 2x + 3y - \(9.3 \bar 5\) = 0 with ax + by + c = 0
We get,
a = 2
b = 3
c = - \(9.3 \bar 5\)
(ii) x –(y/5)–10 = 0
The equation x –(y/5) - 10 = 0 can be written as,
1x + (-1/5)y + (–10) = 0
Now comparing x + (-1/5)y + (–10) = 0 with ax + by + c = 0
We get,
a = 1
b = -(1/5)
c = -10
