Stephanie is x years old. Tobi is twice as old as Stephanie. Ulrika is 3 years younger than Tobi. The sum of all their ages is 5

Marat540 [252]

Answer:

$x=11$

Step-by-step explanation:

Stephanie is $x$ years old.

Tobie is $2x$ years old.

Ulrika is $2x-3$ years old.

$x+2x+2x-3=52$

$5x-3=52$

$5x=52+3$

$5x=55$

$\frac{5x}{5} =\frac{55}{5}$

$x=11$
