We have equation:
t=20x+31
x is number of years after 1997.
To calculate number of laptops in 2005:
x=2005-1997
x=8
t=20*8+31
t=160+31
t=191
In year 2005 school had 191 laptops.

Step-by-step explanation:
2x+y=8x-y=4
First solve take all x variable to one side and all the y on one
y+y=8x-2x=4
2y=6x=4
Solve for x solve for y
6x=4 2y=4
x=4÷6 y=2
x=4/6
