Solving one step equation
2 1/2 + b = 3 1/4
You have to do the opposite operation! It's a little confusing to write, so google this:

He's really easy to follow along with!
It's the the third link, it'll say "One-step addition & subtraction equations" I hope this helps.
subtract 2 1/2 from both sides. That gives you
b = 3 1/4 - 2 1/2
now simplify:
b = 3/4
To solve the one-step equation 2 1/2 + b = 3 1/4, you need to isolate the variable "b" on one side of the equation. Here's how you can do it step by step:
Step 1: Convert the mixed numbers into improper fractions.
2 1/2 can be written as (2 * 2 + 1) / 2 = 5/2
3 1/4 can be written as (3 * 4 + 1) / 4 = 13/4
Step 2: Rewrite the equation with the improper fractions.
5/2 + b = 13/4
Step 3: To eliminate the fractions, you can find a common denominator, which in this case is 4. Multiply both sides of the equation by 4 to get rid of the denominators.
4 * (5/2 + b) = 4 * (13/4)
20/2 + 4b = 52/4
Step 4: Simplify the equation.
10 + 4b = 13
Step 5: Isolate the variable "b" by moving the constant term to the other side of the equation. To do that, subtract 10 from both sides.
10 + 4b - 10 = 13 - 10
4b = 3
Step 6: Solve for "b" by dividing both sides by the coefficient of "b," which is 4.
4b / 4 = 3 / 4
b = 3/4
Therefore, the solution to the equation 2 1/2 + b = 3 1/4 is b = 3/4.
