Richard and Teo have a combined age of 39. Richard is 3 years older than twice Teo's age. How old are Richard and Teo

Teo: 12

Richard: 27

Step-by-step explanation:

Teo's age = x

Richard = 2x+3 (three years older than twice Teo's age)

If Richard+Teo=39 then x+2x+3=39

solve

3x=36

x=12

If Richard is 2x+3 then do 12*2+3=27
