y=\frac{-2\left(-40\right)}{17}-1
Express -2\left(-\frac{40}{17}\right) as a single fraction.
y=\frac{80}{17}-1
Multiply -2 and -40 to get 80.
y=\frac{80}{17}-\frac{17}{17}
Convert 1 to fraction \frac{17}{17}.
y=\frac{80-17}{17}
Since \frac{80}{17} and \frac{17}{17} have the same denominator, subtract them by subtracting their numerators.
y=\frac{63}{17}
Subtract 17 from 80 to get 63.
