Isolate variable terms: Isolate the variable terms on one side of the equation.We want to get all the terms with r on one side and the constant terms on the other side. To do this, we can add 6r to both sides of the equation to move the −6r term to the left side.−10−5r+6r=−6r−1+6rThis simplifies to:−10+r=−1
Add 6r to both sides: Isolate the variable r on one side.Now we want to solve for r by getting it alone on one side of the equation. We can do this by adding 10 to both sides of the equation to move the −10 to the right side.−10+r+10=−1+10This simplifies to:r=9
