Question

$if \: x = \frac{1}{3} is \: a \: solution \: of \: the \: equation \: a {x}^{2} + (a - 1)x + 4 = a.what \: is \: the \: value \: of \: a$
​

Answer 1

Answer:

1/9a + 1/3a - 1/3 + 4 = a

a+3a/9 - 1+12/4 = a

4a/9+11/4 = a

11/4 = a - 4a/9

11/4 = 9a -4a/9

11/4 = 5a/9

11/4 × 9/5 = a

99/20 = a
