To solve for y in the equation 270/y-2=28, we first need to isolate y on one side of the equation.

Step 1: Add 2 to both sides of the equation to get rid of the -2 on the left side:

270/y = 28 + 2
270/y = 30

Step 2: Multiply both sides by y to get rid of the fraction:

270 = 30y

Step 3: Divide both sides by 30 to solve for y:

y = 9

Therefore, the solution to the equation 270/y-2=28 is y = 9.
