Step-by-step explanation: To solve for y in the equation 5y - 2 = 18, we need to isolate y on one side of the equation. We can do that by adding 2 to both sides of the equation:
5y - 2 + 2 = 18 + 2
Simplifying both sides, we get:
5y = 20
Finally, we can solve for y by dividing both sides by 5:
5y/5 = 20/5
Simplifying again:
y = 4
Therefore, the solution to the equation 5y - 2 = 18 is y = 4.
