12a+a=25+1

13a=26

a=26:13

a=2

Answer 2

To solve the equation 12a - 1 = -a + 25, you need to isolate the variable 'a' on one side of the equation. Here's the step-by-step solution:

Step 1: Combine like terms Add 'a' to both sides of the equation to bring the 'a' terms on one side:

12a - 1 + a = -a + a + 25

This simplifies to:

13a - 1 = 25

Step 2: Get rid of the constant term Add 1 to both sides of the equation to isolate the '13a' term:

13a - 1 + 1 = 25 + 1

This simplifies to:

13a = 26

Step 3: Solve for 'a' To get the value of 'a', divide both sides by 13:

a = 26 / 13

This simplifies to:

a = 2

So, the solution to the equation is:

a = 2
