Answer 2

To solve each of these equations for 'x,' you'll need to perform the necessary operations to isolate 'x' on one side of the equation. Here's how you can solve each of the equations step by step:

1. 2x = 18 - x

Add 'x' to both sides to get 'x' terms on one side:

2x + x = 18

Combine like terms:

3x = 18

Now, divide both sides by 3 to solve for 'x':

3x/3 = 18/3

x = 6

2. 4x = 24 + x

Subtract 'x' from both sides to get 'x' terms on one side:

4x - x = 24

Combine like terms:

3x = 24

Now, divide both sides by 3 to solve for 'x':

3x/3 = 24/3

x = 8

3. 7x + 3 = 30 - 2x

Add '2x' to both sides to get 'x' terms on one side:

7x + 3 + 2x = 30

Combine like terms:

9x + 3 = 30

Subtract 3 from both sides to isolate '9x':

9x = 30 - 3

9x = 27

Now, divide both sides by 9 to solve for 'x':

9x/9 = 27/9

x = 3

4. 8x - 8 = 20 - 6x

Add '6x' to both sides to get 'x' terms on one side:

8x + 6x - 8 = 20

Combine like terms:

14x - 8 = 20

Add 8 to both sides to isolate '14x':

14x = 20 + 8

14x = 28

Now, divide both sides by 14 to solve for 'x':

14x/14 = 28/14

x = 2

5. 5 - 2(x - 1) = 4 - x

Distribute the -2 on the left side of the equation:

5 - 2x + 2 = 4 - x

Combine like terms:

5 + 2 - 2x = 4 - x

7 - 2x = 4 - x

Now, add '2x' to both sides to get 'x' terms on one side:

7 - 2x + 2x = 4 - x + 2x

7 = 4 + x

Subtract 4 from both sides to isolate 'x':

7 - 4 = x

3 = x

6. 4 - 6(x + 2) = 3 - 5x

Distribute the -6 on the left side of the equation:

4 - 6x - 12 = 3 - 5x

Combine like terms:

4 - 12 - 6x = 3 - 5x

-8 - 6x = 3 - 5x

Now, add '6x' to both sides to get 'x' terms on one side:

-8 - 6x + 6x = 3 - 5x + 6x

-8 = 3 + x

Subtract 3 from both sides to isolate 'x':

-8 - 3 = x

-11 = x
