Question

5a-1/3(a+1)=6(a+1/30)​

Answer 1

Step-by-step explanation:

Given:-

$\frac{5a - 1}{3(a + 1)} = 6( \frac{a + 1}{30} ) \\ \\ as \: per \: que \\ \\ \frac{5a - 1}{3a + 3} = \frac{a + 1}{5} \\ \\ cross \: multiply \: this \\ \\ 5(5a - 1) = (a + 1)(3a + 3) \\ \\ 25a - 5 = 3 {a}^{2} + 3a + 3a + 3 \\ \\ 25a - {3a}^{2} - 6a - 5 - 3 = 0 \\ \\ 25a - 3 {a}^{2} - 6a - 8 = 0 \\ \\ - 3 {a}^{2} + 19a - 8 = 0 \\ \\ 3 {a}^{2} - 19a + 8 = 0$
