Divide by 3: We have the equation −18=3y. To solve for y, we need to isolate y on one side of the equation. We can do this by dividing both sides of the equation by the coefficient of y, which is 3.Calculation: −18/3=3y/3
Calculate value of y: Perform the division on both sides of the equation to find the value of y.Calculation: −18/3=−6 and 3y/3=ySo, y=−6.
