Question

(2x - 1/2 - 1/6y ) - ( 1/2xy - 1/9y + 1/4x) como fazer essa conta precisa de calculo para eu entender

Answer 1

(2x - 1/2 - 1/6 y) - (1/2 xy - 1/9 y + 1/4 x)

2x - 1/2 - 1/6 y - 1/2 xy + 1/9 y - 1/4 x

2x/1 - x/4 - 1/2 - 1/6 y + 1/9 y - 1/2 xy

(4 . 2x)/(4 . 1) - x/4 - 1/2 - y/6 + 1/9 y - 1/2 xy

8x/4 - x/4 - 1/2 - 3y/(3 . 6) + 2y/(2 . 9) - 1/2 xy

(8x - x)/4 - 1/2 - 3y/18 + 2y/18 - 1/2 xy

7x/4 - 1/2 - 3y/18 + 2y/18 - 1/2 xy

7/4 x - 1/2 (- 3y + 2y)/18 - 1/2 xy

7/4 x - 1/2 - y/18 - 1/2 xy

Answer 2

Explicação passo-a-passo:

$(2x - \frac{1}{2} - \frac{y}{6} ) - ( \frac{xy}{2} - \frac{y}{9} + \frac{x}{4} ) =$

$mmc = 36$

$72x - 18 - 6y - 18xy - 4y + 9x = 81x - 18xy - 10y - 18$
