Sam is 9 years older than twice tim's age. sam is 35 years old. how old is tim.

tim is 13.

let tim's age be t and sam s.

the statement implies 2t + 9 = s.

solving,

 2t + 9=35;

 2t = 35-9;

2t =26; hence t is 13

angle addition postulate

2x=56

step-by-step explanation:

because linear equations are a lot simpler than quadratics equations, and linear equations formula is a lot easier to memorize. that's why i think they're harder.
