10\left(r+37\right)=320
Variable r cannot be equal to -37 since division by zero is not defined. Multiply both sides of the equation by r+37.
10r+370=320
Use the distributive property to multiply 10 by r+37.
10r=320-370
Subtract 370 from both sides.
10r=-50
Subtract 370 from 320 to get -50.
r=\frac{-50}{10}
Divide both sides by 10.
r=-5
Divide -50 by 10 to get -5.
