Given System of Equations: We are given the system of equations:−10−5r=−6r−1Let's isolate the variable r on one side of the equation by adding 6r to both sides.−10−5r+6r=−6r−1+6rThis simplifies to:−10+r=−1
Isolate Variable r: Now, let's isolate r completely by adding 10 to both sides of the equation.−10+r+10=−1+10This simplifies to:r=9
