Math Problem Statement

Solve the following equation for x.

Express your answer in the simplest form.

2x-5=-3 2x+3)

Solution

Let's solve the equation 2x5=3(2x+3)2x - 5 = -3(2x + 3).

Step 1: Distribute the 3-3 on the right side

2x5=6x92x - 5 = -6x - 9

Step 2: Move all the xx terms to one side and the constants to the other side

Add 6x6x to both sides: 2x+6x5=92x + 6x - 5 = -9 8x5=98x - 5 = -9

Step 3: Add 5 to both sides to isolate the xx term

8x=9+58x = -9 + 5 8x=48x = -4

Step 4: Solve for xx by dividing both sides by 8

x=48x = \frac{-4}{8} x=12x = -\frac{1}{2}

So, the solution is x=12x = -\frac{1}{2}.

  1. How would the solution change if the equation were 2x5=3(2x3)2x - 5 = -3(2x - 3)?
  2. What is the value of xx if the equation is 2x+5=3(2x+3)2x + 5 = -3(2x + 3)?
  3. Can you solve 4x7=2(2x+5)4x - 7 = -2(2x + 5) for xx?
  4. What happens if you substitute x=12x = -\frac{1}{2} back into the original equation?
  5. How would you solve 3x9=4(2x+6)3x - 9 = -4(2x + 6)?

Tip: When dealing with negative signs in front of parentheses, be careful to distribute the sign correctly to avoid errors.
