Math Problem Statement

1/2x-5=10-3/4x

Solution

Let's solve the equation 12x5=1034x\frac{1}{2}x - 5 = 10 - \frac{3}{4}x.

Step-by-Step Solution:

  1. Eliminate the fractions: Multiply the entire equation by 4, the least common denominator (LCD) of 2 and 4, to get rid of the fractions: 4×(12x5)=4×(1034x)4 \times \left( \frac{1}{2}x - 5 \right) = 4 \times \left( 10 - \frac{3}{4}x \right) This simplifies to: 2x20=403x2x - 20 = 40 - 3x

  2. Move all terms with xx to one side: Add 3x3x to both sides to bring the terms with xx on one side: 2x+3x20=402x + 3x - 20 = 40 Simplifying: 5x20=405x - 20 = 40

  3. Isolate xx: Add 20 to both sides: 5x=605x = 60

  4. Solve for xx: Divide both sides by 5: x=12x = 12

Final Answer:

x=12x = 12
