Answer:
x + y = 26
x = y + 8
(Note: if the options are different, try manipulating the above equations to the options)
Explanation:
let x = number of boys and y = number of girls
Since the total number of students is 26
boys + girls = 26,
x + y = 26
Also, there are 8 more boys than girls,
so, boys = girls + 8
x = y + 8
so the system of equations is,
x + y = 26
x = y+8
