Math Problem Statement

What value of x makes the equation 2x - (5x - 3) = -3(2x + 4) true?

Solution

The equation provided is:

2x(5x3)=3(2x+4)2x - (5x - 3) = -3(2x + 4)

Let's solve for xx.

Step 1: Simplify both sides of the equation

Start by distributing the negative sign on the left-hand side and the 3-3 on the right-hand side:

2x5x+3=6x122x - 5x + 3 = -6x - 12

Step 2: Combine like terms

Simplify the equation by combining like terms on the left side:

3x+3=6x12-3x + 3 = -6x - 12

Step 3: Move all xx-terms to one side and constants to the other side

Add 6x6x to both sides to get all xx-terms on the left:

3x+6x+3=12-3x + 6x + 3 = -12

This simplifies to:

3x+3=123x + 3 = -12

Now, subtract 3 from both sides:

3x=153x = -15

Step 4: Solve for xx

Divide both sides by 3:

x=5x = -5

Conclusion:

The value of xx that makes the equation true is x=5x = -5.
