Answer 1

Ответ:

1) -8x=-24

-x=-3; x=3

2)2x=24+8

2x=32

x=16

3)4x=22

x=5.5

5)9y=27

y=3

6)10x=12+8-6

10x=14

x=1.4

7)4x-2x-14=6-2x

2x+2x=6+14

4x=20

x=5

Answer 2

Let's solve each equation step by step:

1. -3x - 5x = -16 - 8

Combining like terms: -8x = -24

Dividing both sides by -8: x = 3

2. 2x - 8 = 24

Adding 8 to both sides: 2x = 32

Dividing both sides by 2: x = 16

3. 4x + 7 = 15

Subtracting 7 from both sides: 4x = 8

Dividing both sides by 4: x = 2

4. -3x - 5x = -16 - 8

Combining like terms: -8x = -24

Dividing both sides by -8: x = 3

5. 8y + y = 18 + 9

Combining like terms: 9y = 27

Dividing both sides by 9: y = 3

6. -8 + 6 = -10x + 12

Simplifying both sides: -2 = -10x + 12

Subtracting 12 from both sides: -14 = -10x

Dividing both sides by -10: x = 1.4

7. 4x - 2(x + 7) = 2(3 - x)

Expanding and simplifying both sides: 4x - 2x - 14 = 6 - 2x

Combining like terms: 2x - 14 = 6 - 2x

Adding 2x to both sides: 4x - 14 = 6

Adding 14 to both sides: 4x = 20

Dividing both sides by 4: x = 5

So, the solutions to the given equations are:

1. x = 3
2. x = 16
3. x = 2
4. x = 3
5. y = 3
6. x = 1.4
7. x = 5
