Question

1) 6x = 28 - x; 2) 9x - 26 = 30 - 5x; 3) 5(x - 4) = x + 8; 4) 9 - 7(x + 3) = 5 - 6x;

Answer 1

Ответ:

1) 6х + х = 28

7х = 28

х=4

2)9х+5х=30+26

14х=56

х=4

3)5х-20=х+8

5х-х=8+20

4х=28

х=7

4)9-7х-21=5-6х

-7х+6х=5+21-9

Answer 2

Пошаговое объяснение:

1) 6х = 28 - х

7х = 28

х = 4

2) 9х - 26 = 30 - 5х

14х = 56

х = 4

3) 5(х - 4) = х + 8

5х - 20 = х + 8

4х = 28

х = 7

4) 9 - 7(х + 3) = 5 - 6х

9 -7х -21 = 5 - 6х

-х = 17

х = -17

Answer 3

It looks like you've provided four equations. If you need help solving them, I can certainly assist you. I'll solve each equation step by step:

1. 6x = 28 - x

Add 'x' to both sides: 6x + x = 28 7x = 28

Divide both sides by 7: x = 28 / 7 x = 4

So, the solution for this equation is x = 4.

2. 9x - 26 = 30 - 5x

Add '5x' to both sides and add '26' to both sides: 9x + 5x = 30 + 26 14x = 56

Divide both sides by 14: x = 56 / 14 x = 4

So, the solution for this equation is x = 4.

3. 5(x - 4) = x + 8

Distribute '5' on the left side: 5x - 20 = x + 8

Subtract 'x' from both sides: 5x - x - 20 = 8 4x - 20 = 8

Add '20' to both sides: 4x = 28

Divide both sides by 4: x = 28 / 4 x = 7

So, the solution for this equation is x = 7.

4. 9 - 7(x + 3) = 5 - 6x

Distribute '7' on the left side: 9 - 7x - 21 = 5 - 6x

Combine the constants on the left side: -12 - 7x = 5 - 6x

Add '7x' to both sides and subtract '5' from both sides: -12 = 12 - 6x

Subtract '12' from both sides: -24 = -6x

Divide both sides by -6: x = 4

So, the solution for this equation is x = 4.

To summarize:

1. x = 4
2. x = 4
3. x = 7
4. x = 4
