170\left(R+1\right)=180R
Variable R cannot be equal to -1 since division by zero is not defined. Multiply both sides of the equation by R+1.
170R+170=180R
Use the distributive property to multiply 170 by R+1.
170R+170-180R=0
Subtract 180R from both sides.
-10R+170=0
Combine 170R and -180R to get -10R.
-10R=-170
Subtract 170 from both sides. Anything subtracted from zero gives its negation.
R=\frac{-170}{-10}
Divide both sides by -10.
R=17
Divide -170 by -10 to get 17.
