1. Problem Description

Solve the following two equations for xx.
Equation 13: 213x24=x162\frac{1}{3} - \frac{x-2}{4} = \frac{x-1}{6}
Equation 15: 2x55x+2=322\frac{2x-5}{5x+2} = \frac{3}{22}

2. Solution Steps

Solving Equation 13: 213x24=x162\frac{1}{3} - \frac{x-2}{4} = \frac{x-1}{6}
Step 1: Convert the mixed number to an improper fraction.
213=2×3+13=732\frac{1}{3} = \frac{2 \times 3 + 1}{3} = \frac{7}{3}
The equation becomes:
73x24=x16\frac{7}{3} - \frac{x-2}{4} = \frac{x-1}{6}
Step 2: Find the least common multiple (LCM) of the denominators 3, 4, and

6. The LCM is

1
2.
Step 3: Multiply both sides of the equation by the LCM,
1

2. $12(\frac{7}{3} - \frac{x-2}{4}) = 12(\frac{x-1}{6})$

12(73)12(x24)=12(x16)12(\frac{7}{3}) - 12(\frac{x-2}{4}) = 12(\frac{x-1}{6})
4(7)3(x2)=2(x1)4(7) - 3(x-2) = 2(x-1)
283x+6=2x228 - 3x + 6 = 2x - 2
Step 4: Simplify and solve for xx.
343x=2x234 - 3x = 2x - 2
34+2=2x+3x34 + 2 = 2x + 3x
36=5x36 = 5x
x=365x = \frac{36}{5}
Solving Equation 15: 2x55x+2=322\frac{2x-5}{5x+2} = \frac{3}{22}
Step 1: Cross-multiply.
22(2x5)=3(5x+2)22(2x-5) = 3(5x+2)
Step 2: Expand both sides.
44x110=15x+644x - 110 = 15x + 6
Step 3: Solve for xx.
44x15x=6+11044x - 15x = 6 + 110
29x=11629x = 116
x=11629x = \frac{116}{29}
x=4x = 4

3. Final Answer

For equation 13: x=365x = \frac{36}{5}
For equation 15: x=4x = 4
