Question

решение уравнения 1)4x+6/2+9=2x/3 2). 2x+5/6+4=4x/7 3).4x+4/3-2x=2

Answer 1

1)

$4x + 3 + 9 = frac{2x}{3}$

$4x + 12 = frac{2x}{3}$

$12x + 36 = 2x$

$12x - 2x = - 36$

$10x = - 36$

2)

$2x + frac{29}{6} = frac{4x}{7}$

$84x + 203 = 24x$

$84x - 24x = - 203$

$60x = - 203$

3)

$2x + frac{4}{3}$

$frac{1}{3} times (6x + 4)$

$frac{1}{3} times 2(3x + 2)$

$2 times frac{1}{3} times (3x + 2)$

$frac{2}{3} times (3x + 2)$
