Math Problem Statement

solve this using solving eqution method

Solution

Let's solve the equation shown in the image. The equation is:

34x12=13x+2\frac{3}{4}x - \frac{1}{2} = \frac{1}{3}x + 2

Step 1: Eliminate the fractions by finding a common denominator.

The least common multiple (LCM) of 4, 2, and 3 is 12. Multiply every term in the equation by 12 to eliminate the fractions:

12×(34x)12×(12)=12×(13x)+12×212 \times \left(\frac{3}{4}x\right) - 12 \times \left(\frac{1}{2}\right) = 12 \times \left(\frac{1}{3}x\right) + 12 \times 2

Step 2: Simplify each term.

9x6=4x+249x - 6 = 4x + 24

Step 3: Move the terms involving xx to one side and constant terms to the other side.

Subtract 4x4x from both sides:

9x4x6=249x - 4x - 6 = 24

5x6=245x - 6 = 24

Step 4: Isolate xx.

Add 6 to both sides:

5x=305x = 30

Divide by 5:

x=6x = 6

Solution:

The value of xx is 6\boxed{6}.

Would you like any further details or have any questions about this solution?

Here are five related questions to deepen your understanding:

  1. How would the solution change if the constant term on the right side was different?
  2. Can you solve the equation using a different method, such as graphing?
  3. What happens if you multiply each term by a different common multiple?
  4. How would you check if x=6x = 6 is indeed the correct solution?
  5. What if the fractions had different numerators and denominators, how would that affect the process?

Tip: When solving equations with fractions, multiplying by the least common multiple can simplify the equation and make it easier to solve.
