Eva has read 141 pages and Liam has read 124 pages.

Step-by-step explanation:

Let,

Pages read by Eva = x

Pages read by Liam = y

According to given statement;

x+y=265 Eqn 1

y=x-17 Eqn 2

Putting value of y from Eqn 2 in Eqn 1

$x+(x-17)=265\\x+x-17=265\\2x-17=265\\2x=265+17\\2x=282$

Dividing both sides by 2

$\frac{2x}{2}=\frac{282}{2}\\x=141$

Putting x=141 in Eqn 2

$y=141-17\\y=124$

Eva has read 141 pages and Liam has read 124 pages.
