What value of a is a solution to this equation? 5a = 15 Choices: (A)a = 3 (B)a = 5

Identify Operation: Identify the operation needed to solve for a. The equation is 5a = 15, which means 5 times a is equal to 15. To solve for a, we need to perform the inverse operation of multiplication, which is division.Divide by 5: Divide both sides of the equation by 5 to isolate a. To get a by itself, we divide both sides of the equation by 5. This gives us a = 15 / 5.Perform Division: Perform the division to find the value of a. Calculating the division, we get a = 3.Check Solution: Check the solution by substituting the value of a back into the original equation. Substituting a = 3 into the original equation gives us 5 * 3 = 15, which simplifies to 15 = 15. This is true, so a = 3 is the correct solution.
