A person(let's call him R)'s mother(let's call her Q)'s age is 49. We can say that Q is 4 years older than 3 times R's age. What is R's age?​

Answer 1

Answer:

15

Step-by-step explanation:

Q=4+3*R

49=4+3*R

49-4/3

45/3

15

Answer 2

let R = x

according to question, 3x+4=49

=> 3x = 49-4 = 45

=> x = 45 /3 = 15

R's age = 15
