Question

find derivative of f(x) =2x+1/5x-7 by f.p​

Answer 1

$2x + \frac{1}{5} x - 7 \\ 2x + \frac{1x}{5} - 7 \\ 2x + \frac{x}{5} - 7 \\ \frac{5 \times 2x}{5} + \frac{x}{5} + \frac{5( - 7)}{5} \\ \frac{5 \times 2x + x + 5( - 7)}{5} \\ \frac{10x + x + 5( - 7)}{5} \\ \frac{10x + x - 35}{5} \\ \frac{11x - 35}{5}$
