Answer:

$\frac{-117}{10}$

Step-by-step explanation:

1) Change the mixed fractions into improper fractions:

$-3\frac{1}{5} + (-8\frac{1}{2} )\\= \frac{-16}{5} - \frac{17}{2}$

2) Multiply the first fraction by 2/2 and the second fraction by 5/5 in order to create common factors on the denominator (You can do this because you are essentially multiplying by one, for example 2/2 = 1):

$\frac{-16}{5} *\frac{2}{2} - \frac{-17}{2} * \frac{5}{5} \\ =\frac{-32}{10} - \frac{85}{10}$

3) Simplify the numerator(top part) while keeping the denominator(bottom part) the same:

$\frac{-32}{10} -\frac{85}{10} \\\\=\frac{-32 - 85}{10}\\ \\= \frac{-117}{10}$

The standard form of a linear equation is

Ax+By=C.

Rewrite the equation with the sides flipped.

x−4=y

Move all terms containing variables to the left side of the equation.

Tap for more steps...

x−y−4=0 Add 4

to both sides of the equation.
