Question

9 ( x+2) =11 (2y -3) e 4 ( 1 -2x ) =5 (1 - y ) +3

Answer 1

Bom Dia

1-)
$9(x + 2) = 11(2y - 3)$

$9x + 18 = 22y - 33$

$9x = 22y - 33 - 18$

$9x = 22y - 51$

$x = \frac{22}{9} y - \frac{51}{9}$

$x = \frac{22}{9} y - \frac{17}{3}$

$x = \frac{22}{9} y - \frac{17}{3} .yer$

2-)
$4(1 - 2x) = 5(1 - y) + 3$

$4 - 8x = 5 - 5y + 3$

$4 - 8x = 8 - 5y$

$- 8x = 8 - 5y - 4$

$- 8x = 4 - 5y$

$x = - \frac{4}{8} + \frac{5}{8} y$

$x = - \frac{1}{2} + \frac{5}{8} y$

$x = - \frac{1}{2} + \frac{5}{8} y.yer$

Espero ter ajudado e bons estudos :)
