Math Problem Statement
What value of x makes the equation 2x - (5x - 3) = -3(2x + 4) true?
Solution
The equation provided is:
Let's solve for .
Step 1: Simplify both sides of the equation
Start by distributing the negative sign on the left-hand side and the on the right-hand side:
Step 2: Combine like terms
Simplify the equation by combining like terms on the left side:
Step 3: Move all -terms to one side and constants to the other side
Add to both sides to get all -terms on the left:
This simplifies to:
Now, subtract 3 from both sides:
Step 4: Solve for
Divide both sides by 3:
Conclusion:
The value of that makes the equation true is .
