Помогите плиз 1) 9х -16 = 2; 2) 4 - 2у = 24; 3) 6х = 32 - 2х; 4) -2у = 4у + 24; 5) 3х - 8 = х; 6) -20 = 4y + 8; 7) 5х + 4 = 3х - 12; 8) -у + 25 = 12у - 1; 9) 10 = 4z - 2-2z; 10) -2 = 3х+ 14 + х; 11) 10y + 6 = 12y - 8; 12) 11z - 3 = -3 - 12z.

Answer 1

Ответ:

1)9x-16=2

9x=16+2

X=18:9

X=2

2)4-2y=24

-2y=24-4

y=20:(-2)

y=-10

6x=32-2x

8x=32

x=4

Answer 2

Ответ:

1)9х=18

х=18:9

х=2

2)-2у=24-4

-2у=20

у=20:(-2)

у=-10

3)6х+2х=32

8х=32

х=32:8

х=4

Answer 3

1) 9x - 16 = 2 To solve for x, we need to isolate the variable on one side of the equation. Adding 16 to both sides: 9x = 2 + 16 9x = 18 Dividing both sides by 9: x = 18/9 x = 2

2) 4 - 2y = 24 Subtracting 4 from both sides: -2y = 24 - 4 -2y = 20 Dividing both sides by -2: y = 20/-2 y = -10

3) 6x = 32 - 2x Combining like terms: 6x + 2x = 32 8x = 32 Dividing both sides by 8: x = 32/8 x = 4

4) -2y = 4y + 24 Adding 2y to both sides: 0 = 6y + 24 Subtracting 24 from both sides: -24 = 6y Dividing both sides by 6: y = -24/6 y = -4

5) 3x - 8 = x Subtracting x from both sides: 2x - 8 = 0 Adding 8 to both sides: 2x = 8 Dividing both sides by 2: x = 8/2 x = 4

6) -20 = 4y + 8 Subtracting 8 from both sides: -28 = 4y Dividing both sides by 4: y = -28/4 y = -7

7) 5x + 4 = 3x - 12 Subtracting 3x from both sides: 2x + 4 = -12 Subtracting 4 from both sides: 2x = -16 Dividing both sides by 2: x = -16/2 x = -8

8) -y + 25 = 12y - 1 Adding y to both sides: 25 = 13y - 1 Adding 1 to both sides: 26 = 13y Dividing both sides by 13: y = 26/13 y = 2

9) 10 = 4z - 2 - 2z Combining like terms: 10 = 2z - 2 Adding 2 to both sides: 12 = 2z Dividing both sides by 2: z = 12/2 z = 6

10) -2 = 3x + 14 + x Combining like terms: -2 = 4x + 14 Subtracting 14 from both sides: -16 = 4x Dividing both sides by 4: x = -16/4 x = -4

11) 10y + 6 = 12y - 8 Subtracting 10y from both sides: 6 = 2y - 8 Adding 8 to both sides: 14 = 2y Dividing both sides by 2: y = 14/2 y = 7

12) 11z - 3 = -3 - 12z Adding 12z to both sides: 11z + 12z - 3 = -3 Combining like terms: 23z - 3 = -3 Adding 3 to both sides: 23z = 0 Dividing both sides by 23: z = 0/23 z = 0
