Answer
$$\frac{1}{3}$$ or $$0.33$$
Work Step by Step
Step 1:
Substitute $x=-1$ and $y=5$
$\frac{y-4x}{3x-6xy}$
$\frac{5-4(-1)}{3(-1)-6(-1)(5)}$
Step 2:
Remember the order of operations.
Parenthesis, Exponents, Multiplication/Division, Addition/Subtraction
So, first
Parenthesis
$\frac{5+4}{-3+30}$
Step 3:
Next,
Add/Subtract in both the denominator and numerator.
$\frac{9}{27}$
Step 4:
Divide
$\frac{1}{3}$ or $0.33$
