Question

Add -4/y + 12/y. Reduce, if possible.

8/y
- 4/y
-4y+12/y
4/y

Answer 1

To combine the fractions \(-\frac{4}{y} + \frac{12}{y}\), you can add the numerators while keeping the denominator the same.

Here’s how it works step by step:

1. Combine the fractions:
\[
-\frac{4}{y} + \frac{12}{y} = \frac{-4 + 12}{y}
\]

2. Simplify the numerator:
\[
-4 + 12 = 8
\]
So, you have:
\[
\frac{8}{y}
\]

Thus, the reduced form of \(-\frac{4}{y} + \frac{12}{y}\) is:
\[
\frac{8}{y}
\]
