Addition of 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+6r
Simplify the equation: Now, we simplify the equation by combining like terms. −10+r=−1
Isolate r: Next, we isolate r by adding 10 to both sides of the equation.−10+r+10=−1+10
Find the value of r: Finally, we simplify the equation to find the value of r.r=9
