Isolate term with r: First, we want to isolate the term containing r on one side of the equation. To do this, we add 65 to both sides of the equation to cancel out the −65 on the left side.9r−65+65=−60+65
Simplify both sides: Now, we simplify both sides of the equation. 9r=5
Get rid of division: To solve for r, we need to get rid of the division by 9. We do this by multiplying both sides of the equation by 9.9r×9=5×9
Find value of r: After performing the multiplication, we find the value of r.r=45
