Question

18/5+х=3/2Х=? 7/3=2х-11 /9Х =? ​

Answer 1

Ответ:

вот. там все подробно расписано

Answer 2

Ответ:

1) -21/10 или -2,1 2)16/9    или 1.7

Пошаговое объяснение:

18/5+х=3/2

x=3/2-18/5

x=-21/10

x=-2.1

2)7/3=2х-11 /9

-2x=-11/9-7/3

-2x=-32/9

x=16/9

x=1.7

Answer 3

It seems like you're looking for solutions to a system of equations involving variables x and Х. Let's solve these step by step:

Equation 1: $\frac{18}{5} + x = \frac{3}{2}Х$

Equation 2: $\frac{7}{3} = 2x - \frac{11}{9}Х$

Let's solve Equation 1 for x:

$x = \frac{3}{2}Х - \frac{18}{5}$

Now, substitute the value of x in Equation 2:

$\frac{7}{3} = 2\left(\frac{3}{2}Х - \frac{18}{5}\right) - \frac{11}{9}Х$

Simplify the equation:

$\frac{7}{3} = 3Х - \frac{36}{5} - \frac{11}{9}Х$

Combine the terms involving Х:

$\frac{7}{3} = \frac{20}{9}Х - \frac{36}{5}$

Now, isolate Х:

$\frac{20}{9}Х = \frac{7}{3} + \frac{36}{5}$

$Х = \frac{\frac{7}{3} + \frac{36}{5}}{\frac{20}{9}}$

Now, calculate the value of Х:

$Х = \frac{35}{12}$

Finally, let's find the value of 3/2Х using the calculated value of Х:

$3/2Х = \frac{3}{2} \times \frac{35}{12} = \frac{105}{24} = \frac{35}{8}$

So, the solutions are: $Х = \frac{35}{12}$ $3/2Х = \frac{35}{8}$
