Answer:

To solve the equation 5x + 15 + 2x = 24 + 4x, you need to isolate the variable "x" on one side of the equation. Here are the steps to solve it:

1. Start by simplifying both sides of the equation by combining like terms:

5x + 2x + 15 = 24 + 4x

(5x + 2x) is the same as 7x, so the equation becomes:

7x + 15 = 24 + 4x

2. Next, you want to move all terms containing "x" to one side of the equation and constants to the other side. To do this, subtract 4x from both sides of the equation:

7x - 4x + 15 = 24

This simplifies to:

3x + 15 = 24

3. Now, isolate the term with "x" by subtracting 15 from both sides:

3x + 15 - 15 = 24 - 15

This simplifies to:

3x = 9

4. Finally, solve for "x" by dividing both sides by 3:

3x / 3 = 9 / 3

This simplifies to:

x = 3

So, the solution to the equation 5x + 15 + 2x = 24 + 4x is x = 3.

Answer:

x = 3

Explanation:

5x + 15 + 2x = 24 + 4x

Add like terms on the left side.

7x + 15 = 24 + 4x

Subtract 4x from both sides.

3x + 15 = 24

Subtract 15 from both sides.

3x = 9

Divide both sides by 3.

x = 3
