Answer:
To figure out if an ordered pair is a solution to an equation, you could perform a test. Identify the x-value in the ordered pair and plug it into the equation. When you simplify, if the y-value you get is the same as the y-value in the ordered pair, then that ordered pair is indeed a solution to the equation.

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
