Question

Richard and Teo have a combined age of 34 . Richard is 10 years older than twice​ Teo's age. How old are Richard and​ Teo?

Answer 1

Answer:

Step-by-step explanation: Richard - R and Teo - T

If Richard and Teo have a combined age of 34, then R+T = 34

Next, Richard is 10 years older than twice Teo's age, or 2T+10 = R

Now you have two equations. The second equation, 2T+10=R tells you what R is equal to so now you can substitute the equation in the first equation, R+T=34

Giving you the equation, 2T+10+T=34

1. isolate and combine your variables - 3T = 24

2. use the order of operations to solve - divide 24 by 3 = 8

So, Teo is 8 years old, making Richard{ (2)(8)+10 = 26}

Ask, is 8 + 26 = 34
