Answers
Answer:- The equation formed in this situation is => x+x+278 = 400
Given in the question:-
Given the total number of students in a school = 400
The number of girls is given = x
And number of boys are = x+278
It is asked to form equation for the given situation. So, the equation formed according to question is
x+x+278 = 400
To find the number of girls and boys, let us solve the equation formed for the given situation
x+x+278 = 400
2x+287 = 400
2x = 400-278
x = 122/2
x = 61
Therefore, the number of girls in the school = x
= 61
And the number of boys in the school = x+278
= 61+278
= 339
