Answer 2

To solve the equation -5y = -21/2, you need to isolate the variable y. Follow these steps:

Step 1: Divide both sides by -5 to get y alone on the left side of the equation: -5y / -5 = (-21/2) / -5

Step 2: Simplify the equation: y = 21/2 * (1/5)

Step 3: Perform the multiplication: y = 21/10

So, the solution to the equation is y = 21/10 or 2.1.
