Answer:
Jiri is 22 (and Pamela is 27)
Step-by-step explanation:
Let x = Jiri's age
Then x + 5 = Pamela's age.
If we add the ages together, they said it's 49.
Jiri + Pam = 49
x + x + 5 = 49
combine like terms.
2x + 5 = 49
subtract 5.
2x = 44
divide by 2.
x = 22
So Jiri is 22 and Pamela is 27.
Check:

The graph of a linear function (a line) can be moved around the coordinate grid. This is called a transformation. There are three basic transformations: translation (sliding the line around), reflection (flipping the line), and scaling (stretching the line). You can move (transform) the line vertically or horizontally.
