True.
When you subtract fractions, including those with variables such as x's, you subtract the numerators and keep the common denominator. Here's the general process:
Given two fractions with the same denominator:
\[ \frac{a}{d} - \frac{b}{d} \]
You subtract the numerators and put the result over the common denominator:
\[ \frac{a - b}{d} \]
For example, if you have:
\[ \frac{x}{4} - \frac{3x}{4} \]
You subtract the numerators \( x - 3x = -2x \) and keep the denominator:
\[ \frac{x - 3x}{4} = \frac{-2x}{4} \]
So, the result is:
\[ \frac{-2x}{4} \]
Remember that the fractions must have a common denominator to perform this subtraction directly. If they do not, you need to find a common denominator first.
