Question

me ajudem e pra hoje 3/x - 4 = x + 6/2x

Answer 1

3/x   -   4   =   x   +   6/(2x)
mmc (x e 2x) = 2x

(2x:x.3)/2x - (2x:1.4)/2x = (2x:1.x)/2x + (2x:2x.6)/2x 
6/2x - 8x/2x = 2x²/2x + 6/2x
6 - 8x = 2x² + 6
2x² = - 8x
2x² - 8x = 0
2x.(x - 4) = 0
2x = 0 --> x = 0
x-4 = 0 --> x = -4
S: {0; -4}
