5r+30=-5\left(r-4\right)
Use the distributive property to multiply 5 by r+6.
5r+30=-5r+20
Use the distributive property to multiply -5 by r-4.
5r+30+5r=20
Add 5r to both sides.
10r+30=20
Combine 5r and 5r to get 10r.
10r=20-30
Subtract 30 from both sides.
10r=-10
Subtract 30 from 20 to get -10.
r=\frac{-10}{10}
Divide both sides by 10.
r=-1
Divide -10 by 10 to get -1.
