Question

4/5x-4=3x/4 What is the solution

Answer 1

$\frac{4}{5x} -4=\frac{3x}{4}$

Multiply the equation by 5x

$4-20x=\frac{15x^2}{4}$

Multiply the equation by 4

$15x^2+80x-16=0$

x = -8/3 ±(4 √(23/5))/3

====================================================

If x is in numerator

(4/5) x - 4 = 3x/4

(4 (x - 5))/5 = (3 x)/4

x=80
