Pamela is 5 years younger than Jiri. The sum of their ages is 81. What is Jiri's age?

Jiri is 43 years old

Step-by-step explanation:

Let x be the age of Pamela, and (x+5) be the age of Jri

Expression

x+(x+5)=81

Expand paranthesis

x+x+5=81

Combine like terms

2x+5=81

Subtract 5 on both sides

2x+5-5=81-5

2x=76

Divide 2 on both sides

2x/2=76/2

x=38

Since we've set Jiri's age as (x+5), we need to substitute the value of x

x+5=38+5=43

Hope this helps!! :)
