5=13+y\left(-3\right)
Variable y cannot be equal to 0 since division by zero is not defined. Multiply both sides of the equation by y.
13+y\left(-3\right)=5
Swap sides so that all variable terms are on the left hand side.
y\left(-3\right)=5-13
Subtract 13 from both sides.
y\left(-3\right)=-8
Subtract 13 from 5 to get -8.
y=\frac{-8}{-3}
Divide both sides by -3.
y=\frac{8}{3}
Fraction \frac{-8}{-3} can be simplified to \frac{8}{3} by removing the negative sign from both the numerator and the denominator.
