26. \( \frac{3}{4}=j-\frac{1}{2} \)

To solve for \( j \), start by isolating \( j \) in the equation \( \frac{3}{4} = j - \frac{1}{2} \). You can do this by adding \( \frac{1}{2} \) to both sides. So, you rewrite the equation as \( j = \frac{3}{4} + \frac{1}{2} \). To add the fractions, convert \( \frac{1}{2} \) to have a common denominator of 4, which is \( \frac{2}{4} \). Thus, \( j = \frac{3}{4} + \frac{2}{4} = \frac{5}{4} \). So, \( j \) is \( \frac{5}{4} \) or 1.25. Just like that, you’ve crunched some numbers and found \( j \)! Remember, when you're working with fractions, finding a common denominator is your best friend, and staying organized with neat calculations makes everything clearer. Keep practicing, and soon, these will be second nature to you!
