Combine Like Terms: First, we want to get all the terms with r on one side of the equation and the constant terms on the other side. We can do this by adding 6r to both sides of the equation.−10−5r+6r=−6r−1+6rThis simplifies to:−10+r=−1
Isolate Variable: Next, we want to isolate r by getting rid of the −10 on the left side. We can do this by adding 10 to both sides of the equation.−10+r+10=−1+10This simplifies to:r=9
