+ - 0. 1) (2x + 14 = 6; 2) 9x -18) = 27; 3) 8x + 12 = 20; 4) 15x - 10 = 5; 5) 9x + 15 = 6; 6) 8x - 6 = 14.​

Answer 1

Ответ:

Пошаговое объяснение:

1) 2x + 14 = 6

2х= 6 - 14

2х= -8

х= -4

2) 9x -18 = 27

9х= 27 + 18

9х= 45

х= 45 :9

х= 5

3) 8x + 12 = 20

8х= 20-12

8х= 8

х= 1

4) 15x - 10 = 5

15х= 5+10

15х= 15

х=1

5) 9x + 15 = 6

9х= 6 - 15

9х= -9

х= -1

6) 8x - 6 = 14

8х= 14+6

8х= 20

х= 2,5

Answer 2

1)2x+14=6

2x=6-14

2x=-8

x=-8:2

x=-4

2)9x-18=27

9x=27+18

9x=45

x=45:9

x=5

3)8x+12=20

8x=20-12

8x=8

x=8:8

x=1

4)15x-10=5

15x=5+10

15x=15

x=15:15

x=1

5)9x+15=6

9x=6-15

9x=-9

x=-9:9

x=-1

6)8x-6=14

8x=14+6

8x=20

x=20:8

x=20/8

x=2 4/8

x=2 1/2

Answer 3

It looks like you have a system of linear equations. Let's solve each equation one by one:

1. 2x + 14 = 6 First, let's isolate the variable x. Subtract 14 from both sides of the equation: 2x + 14 - 14 = 6 - 14 2x = -8 Now, divide both sides by 2 to solve for x: 2x / 2 = -8 / 2 x = -4

So, the solution to the first equation is x = -4.

2. 9x - 18 = 27 First, add 18 to both sides of the equation: 9x - 18 + 18 = 27 + 18 9x = 45 Now, divide both sides by 9 to solve for x: 9x / 9 = 45 / 9 x = 5

So, the solution to the second equation is x = 5.

3. 8x + 12 = 20 First, subtract 12 from both sides of the equation: 8x + 12 - 12 = 20 - 12 8x = 8 Now, divide both sides by 8 to solve for x: 8x / 8 = 8 / 8 x = 1

So, the solution to the third equation is x = 1.

4. 15x - 10 = 5 First, add 10 to both sides of the equation: 15x - 10 + 10 = 5 + 10 15x = 15 Now, divide both sides by 15 to solve for x: 15x / 15 = 15 / 15 x = 1

So, the solution to the fourth equation is x = 1.

5. 9x + 15 = 6 First, subtract 15 from both sides of the equation: 9x + 15 - 15 = 6 - 15 9x = -9 Now, divide both sides by 9 to solve for x: 9x / 9 = -9 / 9 x = -1

So, the solution to the fifth equation is x = -1.

6. 8x - 6 = 14 First, add 6 to both sides of the equation: 8x - 6 + 6 = 14 + 6 8x = 20 Now, divide both sides by 8 to solve for x: 8x / 8 = 20 / 8 x = 5/2 or 2.5

So, the solution to the sixth equation is x = 5/2 or 2.5.

In summary:

1. x = -4
2. x = 5
3. x = 1
4. x = 1
5. x = -1
6. x = 5/2 or 2.5
