Answer:
Number of boys = 675
Step-by-step explanation:
Given that:
There are 5 times as many boys as girls in a school.
Number of pupils in school = 810
Let,
x be the number of girls
y be the number of boys
According to given statement;
x+y=810 Eqn 1
y = 5x Eqn 2
Putting y=5x in the Eqn 1
x+5x=810
6x=810
Dividing both sides by 6

Putting x=135 in Eqn 2
y = 5(135)
y = 675
Hence,
Number of boys = 675
Answer: x=3
I got to the answer by doing simple math. Both sides must be even.
5x-4
5(3)-4= 15-4 = 11
x+8
3+8= 11
So x=3
