A way to add fractions that always works is to multiply each numerator by the denominator of the other, then express the sum of products over the product of the denominators.
\dfrac{a}{b}+\dfrac{c}{d}=\dfrac{a}{b}\cdot\dfrac{d}{d}+\dfrac{c}{d}\cdot\dfrac{b}{b}\\\\=\dfrac{ad+bc}{bd}

Here, you have
\dfrac{-5}{4}-\dfrac{-1}{6}=\dfrac{-5\cdot6-(-1)\cdot4}{4\cdot6}=\dfrac{-26}{24}\\\\=\dfrac{-13}{12}=-1\frac{1}{12}

The sum is -1 1/12

Pls help me with this
Illusion [34]

Answer:

No solutions.

Step-by-step explanation:

Both equations have the same slope, but are separated by virtue of their different values of b, the y-intercept.  The same slope means they are parallel lines.  Since the y-intercept is different, they do not overlap.

As they say, "Parallel line have a lot in common.  Too bad they'll never meet."
