plz mark me brainliest
He added two fractions by adding the numerators and adding the denominators. That is incorrect.
To add two fractions, you must first have he same denominator in both.
Then you add the numerators and write the same denominator. You do not add the denominators.

Answer:
x = 118
Step-by-step explanation:
1. All the angles in a pentagon add up to 540, so to find the value of x, we can use this equation x + 122 + 103 + 98 + 99 = 540.
2. (Solving)
Step One: Simplify both sides of the equation by adding like terms.
- (x) + (122 + 103 + 98 + 99) = 540
- x + 422 = 540
Step Two: Subtract 422 from both sides.
- x + 422 - 422 = 540 - 422
- x = 18
