Question

-2*3/8*(-16/57)*1*1\5*х=7*8/9*33/71*(-1*2/5);

Answer 1

Ответ:

$- 2 \times \frac{3}{8} \times ( - \frac{16}{57} ) \times 1 \times \frac{1}{5} \times x = 7 \times \frac{8}{9} \times \frac{33}{71} \times ( - 1 \times \frac{2}{5} )$

$- \frac{3}{4} \times ( - \frac{16}{57} ) \times \frac{1}{5} x = 7 \times \frac{8}{9} \times \frac{33}{71} \times ( - \frac{2}{5} )$

$\frac{4}{19} \times \frac{1}{5} x = - 7 \times \frac{8}{3} \times \frac{11}{71} \times \frac{2}{5}$

$\frac{4}{95} x = - \frac{1232}{1065}$

$x = \frac{5852}{213}$

или

$x = 27 \frac{101}{213}$

Answer 3

Let's break down and solve the equation step by step:

-2 * 3 / 8 * (-16 / 57) * 1 * (1 / 5) * x = 7 * 8 / 9 * 33 / 71 * (-1 * 2 / 5)

First, simplify each side of the equation:

Left side: -2 * 3 / 8 * (-16 / 57) * 1 * (1 / 5) * x

= (-6 / 8) * (-16 / 57) * (1 / 5) * x

Now, let's simplify the fractions:

= (-3 / 4) * (-16 / 57) * (1 / 5) * x

= (3/4) * (16/57) * (1/5) * x

Now, let's simplify the right side of the equation:

7 * 8 / 9 * 33 / 71 * (-1 * 2 / 5)

= (56 / 9) * (33 / 71) * (-2 / 5)

Now, let's multiply these fractions:

= (56 * 33 * (-2)) / (9 * 71 * 5)

= (-3696) / (3195)

Now, the equation becomes:

(3/4) * (16/57) * (1/5) * x = (-3696) / (3195)

Now, we need to solve for x. To isolate x, we can multiply both sides of the equation by the reciprocal of the left side:

x = ((-3696) / (3195)) / ((3/4) * (16/57) * (1/5))

Now, let's simplify the right side:

x = ((-3696) / (3195)) / ((3/4) * (16/57) * (1/5))

To divide by a fraction, multiply by its reciprocal:

x = ((-3696) / (3195)) * ((4/3) * (57/16) * (5/1))

Now, let's perform the multiplication:

x = (-3696) * (4/3) * (57/16) * (5/1) / 3195

Now, simplify:

x = (-924) * (57/16) * (5/1) / 3195

x = (-924) * (285/16) / 3195

Now, multiply the numerators:

x = (-131940) / (16 * 3195)

x = (-131940) / 51120

Now, simplify the fraction:

x ≈ -2.583

So, the solution to the equation is approximately x ≈ -2.583.
