Question

Решите уравнение 3,2×(1 9/16х-5)=-26​

Answer 1

3,2×(1 9/16х-5)=-26

1 9/16 × х - 5 = -8,125

25/16х-5= -8,125

25/16х - 5 = -65/8

25х - 80 = -130

25х= -130+80

25х=-50

х= -2.

Answer 2

$3.2*(1\frac{9}{16}x-5)=-26$

$\frac{32}{10}*\frac{25x}{16}-5*\frac{32}{10}=-26$

$5x-16=-26$

$5x=-10$

$x=-\frac{10}{5}$

$x=-2$

Ответ: х= -2
