Math Problem Statement

1/2 (x-1) + 5 = 1/3 (2x + 1)

Solution

To solve the equation:

12(x1)+5=13(2x+1)\frac{1}{2}(x - 1) + 5 = \frac{1}{3}(2x + 1)

Step 1: Eliminate the fractions

To eliminate the fractions, find the least common denominator (LCD) of 2 and 3, which is 6. Multiply every term by 6:

612(x1)+65=613(2x+1)6 \cdot \frac{1}{2}(x - 1) + 6 \cdot 5 = 6 \cdot \frac{1}{3}(2x + 1)

Simplify each term:

3(x1)+30=2(2x+1)3(x - 1) + 30 = 2(2x + 1)

Step 2: Expand and simplify

Expand both sides of the equation:

3x3+30=4x+23x - 3 + 30 = 4x + 2

Simplify further:

3x+27=4x+23x + 27 = 4x + 2

Step 3: Solve for xx

Isolate xx by subtracting 3x3x from both sides:

27=x+227 = x + 2

Then subtract 2 from both sides:

x=25x = 25

Final Answer:

x=25x = 25
