Answer 2

To solve the equation 5(a + 12) = 12.5a for the variable "a," you can follow these steps:

1. Distribute the 5 on the left side of the equation by multiplying it by both terms inside the parentheses:

5a + 5(12) = 12.5a

2. Simplify the expression on the left side by multiplying 5 by 12:

5a + 60 = 12.5a

3. Now, you want to isolate the variable "a" on one side of the equation. To do this, you can subtract 5a from both sides of the equation:

5a - 5a + 60 = 12.5a - 5a

This simplifies to:

60 = 7.5a

4. Finally, divide both sides by 7.5 to solve for "a":

60 / 7.5 = (7.5a) / 7.5

a = 8

So, the solution to the equation 5(a + 12) = 12.5a is a = 8.
