Answer 2

Ответ:

Пошаговое объяснение:

3x − 1 = 2(x - 2)

3x - 1 = 2x - 4

3x - 2x = -4 + 1

x = -3

3(x+5) = 7 – 5x

3x + 15 = 7 - 5x

3x + 5x = 7 - 15

8x = -8

x = -8 : 8

x = -1

19(y - 9) = 3(y - 8)

19y - 171 = 3y - 24

19y - 3y = 171 - 24

16y = 147

y = 147 : 16

y = 9,1875

4(x - 9) = 3(x-8)

4x - 36 = 3x - 24

4x - 3x = 36 - 24

x = 12

3(2x - 9) = 5(x-4)​

6x - 27 = 5x - 20

6x - 5x = 27 - 20

x = 7

Answer 3

Let's solve each equation step by step:

1. B3x - 1 = 2(x - 2)

Expanding both sides: 3x - B - 1 = 2x - 4

Rearranging the terms: 3x - 2x = 4 - 1 + B x = 3 + B

2. 3(x + 5) = 7 - 5x

Expanding both sides: 3x + 15 = 7 - 5x

Combining like terms: 3x + 5x = 7 - 15 8x = -8

Dividing both sides by 8: x = -1

3. 19(y - 9) = 3(y - 8)

Expanding both sides: 19y - 171 = 3y - 24

Rearranging the terms: 19y - 3y = -24 + 171 16y = 147

Dividing both sides by 16: y = 147/16

4. 4(x - 9) = 3(x - 8)

Expanding both sides: 4x - 36 = 3x - 24

Rearranging the terms: 4x - 3x = -24 + 36 x = 12

5. 3(2x - 9) = 5(x - 4)

Expanding both sides: 6x - 27 = 5x - 20

Rearranging the terms: 6x - 5x = -20 + 27 x = 7

So, the solutions to the given equations are:

1. x = 3 + B
2. x = -1
3. y = 147/16
4. x = 12
5. x = 7
