Question

Please help thank you

Answer 1

OK then let the age of Robert be X

And the age of Z be X-5 (as he is 5 year younger than Robert)

NOW SUM OF THEIR AGES———

X-5 + X = 35
2X + 5 = 35
2X. = 35-5
2X. = 30
X. = 15


HENCE THE AGE OF ROBERT IS 15 AND Z IS 10 ( HE IS 5 YEARS YOUNGER)......

Answer 2

Hey buddy,

Here's your answer

Answer:

Equation: x + ( x - 5 ) = 39

Zhang is 17 years old

Robert is 22 years

Step-by-step explanation:

Let age of Zhang = x - 5

and let age of Robert be x

Acc to question

x + ( x - 5 ) = 39

x + x - 5 = 39

2x = 44

x = 22

And,

x - 5

22-5 = 17

Therefore, Robert's age is 22 years

and Zhang's age is 17 years
