Solution

Let's review the steps to verify the correct solution.

Given Equation:

2x23x+14=x+232\frac{2x}{2} - \frac{3x + 1}{4} = \frac{x + 2}{3} - 2

Simplifying the terms:

  1. Simplify 2x2\frac{2x}{2} to get: xx

  2. The equation then becomes: x3x+14=x+232x - \frac{3x + 1}{4} = \frac{x + 2}{3} - 2

Step 1: Eliminate the Fractions by Multiplying by the LCM

Multiply through by the LCM of the denominators 4 and 3, which is 12:

12(x3x+14)=12(x+232)12 \cdot \left(x - \frac{3x + 1}{4}\right) = 12 \cdot \left(\frac{x + 2}{3} - 2\right)

This results in:

12x3(3x+1)=4(x+2)2412x - 3(3x + 1) = 4(x + 2) - 24

Step 2: Distribute and Simplify

Distribute the numbers across the terms:

12x(9x+3)=4x+82412x - (9x + 3) = 4x + 8 - 24

Simplifying, we get:

12x9x3=4x1612x - 9x - 3 = 4x - 16

Simplify further:

3x3=4x163x - 3 = 4x - 16

Step 3: Solve for xx

Subtract 4x4x from both sides:

3x4x3=163x - 4x - 3 = -16

Simplify:

x3=16-x - 3 = -16

Add 3 to both sides:

x=13-x = -13

Multiply by 1-1:

x=13x = 13

Verification:

To verify if x=13x = 13 is correct, substitute x=13x = 13 into the original equation:

  1. Left Side: 2(13)23(13)+14=1339+14=1310=3\frac{2(13)}{2} - \frac{3(13) + 1}{4} = 13 - \frac{39 + 1}{4} = 13 - 10 = 3

  2. Right Side: 13+232=1532=52=3\frac{13 + 2}{3} - 2 = \frac{15}{3} - 2 = 5 - 2 = 3

Both sides equal 3, confirming that the solution is indeed x=13x = 13.

Conclusion:

The correct solution is x=13x = 13, not x=5x = 5. If there was a mistake, it may have been due to an earlier misinterpretation or a different equation. If you'd like to review another equation or see more examples, feel free to ask!
