Question

solve this equation :
x/3=1/5(x+4)​

Answer 1

$\frac{x}{3} = \frac{1}{5(x + 4)} \\ = > x \times 5(x + 4) = 3 \times 1 \\ = > 5x {}^{2} + 4x = 3 \\ = > 5x { }^{2} + 4x - 3 = 0 \\ = >$

Answer 2

Answer:

x= 6

Explanation:

$\frac{x}{3} = \frac{1}{5} (x + 4) \\ = > 5x = 3(x + 4) \: \: \: \: (multiplying \: both \: sides \: by \: 15 \: i.e. \: lcm \: of \: 3 \: and \: 5) \\ = > 5x = 3x + 12 \\ = > 5x - 3x = 12 \\ = > 2x = 12 \\ = > x = \frac{12}{2} \\ = > x = 6$
