Isolate variable r: First, we want to isolate the variable r on one side of the equation. To do this, we can add 3r to both sides of the equation to move all the r terms to the left side.−5r+3r=−3r+6+3r
Simplify the equation: Now, we simplify the equation by combining like terms on both sides.−5r+3r=−3r+3r+6−2r=6
Solve for r: Next, we solve for r by dividing both sides of the equation by −2 to isolate r.−2−2r=−26r=−3
