Answer: 4/3
Explanation:
To solve the equation 15a + 18 = 38, we need to isolate the variable "a" on one side of the equation.
First, we can subtract 18 from both sides of the equation to get: 15a = 20
Then, we can divide both sides of the equation by 15 to solve for a: a = 4/3
So, the solution to the equation 15a + 18 = 38 is a = 4/3.
