1-6r+3r=-4
Add 3r to both sides.
1-3r=-4
Combine -6r and 3r to get -3r.
-3r=-4-1
Subtract 1 from both sides.
-3r=-5
Subtract 1 from -4 to get -5.
r=\frac{-5}{-3}
Divide both sides by -3.
r=\frac{5}{3}
Fraction \frac{-5}{-3} can be simplified to \frac{5}{3} by removing the negative sign from both the numerator and the denominator.
