Question

Gabrielle is 10 years younger than mikhail. the sum of their ages is 80 . what is mikhail's age?

Answer 1

To do this, first divide 80 in half.  Then, add five to one of the 40 and subtract 5 from one of the 40 to get 35 and 45.  Together, they are 80 years old and their ages are ten years apart.  Mikhail is 45 years old.  Please mark Brainliest!!!

Answer 2

Mikhail's age = x
Grabielle's age = X-10
Mikhail's age + Gabrielle's age = 80
$x + x - 10 = 80$
$2x - 10 = 80$
$2x = 90$
$x = \frac{90}{2}$
$x = 45$
So Mikhail is 45 years old
