To solve the equation 18 + 6y = 90, we need to isolate the variable y.
First, subtract 18 from both sides of the equation:
18 + 6y - 18 = 90 - 18
Simplifying, we have:
6y = 72
Next, divide both sides of the equation by 6:
6y / 6 = 72 / 6
Simplifying further, we get:
y = 12
Therefore, the solution to the equation 18 + 6y = 90 is y = 12.
18 + 6y = 90
