Question

5*(х-3)=4*(8-х)х-6=5х+2х+15=-2х​

Answer 1

• 5×(х-3)=4×(8-х)

5х-15=32-4х

5х+4х=32+15

9х=47

$x = \frac{47}{9}$

• х-6=5х+2

х-5х=2+6

-4х=8

$x = - 2$

• х+15=-2х

х+2х=-15

3х=-15

х=-5

Answer 2

Ответ:

1) х/4+х/3=х/6+5

Приводим к общему знаменателю

(3x+4x)/12=(x+30)/6

Умножим обе части уравнения на 12

7x=2(x+30)

7x=2x+60

5x=60

x=12

2) 2х/3-4х/5=х/15+1

(10x-12x)/15=(x+15)/15

-2x=x+15

-3x=15

x= -5

3) 3х/8-х/6=х/12

(18x-8x)/48=x/12

10x=4x

10x-4x=0

6х=0

х=0

Answer 3

Let's solve each of these equations step by step.

1. 5*(x-3) = 4*(8-x)

First, distribute the constants on both sides of the equation:

5x - 15 = 32 - 4x

Now, add 4x to both sides of the equation:

5x + 4x - 15 = 32

Combine like terms:

9x - 15 = 32

Now, add 15 to both sides to isolate the variable:

9x = 32 + 15 9x = 47

Finally, divide both sides by 9 to solve for x:

x = 47/9

So, the solution for the first equation is x = 47/9.

2. x - 6 = 5x + 2

First, move the terms involving x to one side of the equation and the constants to the other side:

x - 5x = 2 + 6

Now, combine like terms:

-4x = 8

To solve for x, divide both sides by -4:

x = 8 / -4 x = -2

So, the solution for the second equation is x = -2.

3. 2x + 15 = -2x

First, move the terms involving x to one side of the equation:

2x + 2x = -15

Now, combine like terms:

4x = -15

To solve for x, divide both sides by 4:

x = -15 / 4

So, the solution for the third equation is x = -15/4.
