Answer: b= -5 over 3
Step-by-step explanation:
create the equation 3b + 9 = 4
subtract 9 from each side to isolate the variable
we are left with 3b = -5
to further isolate the variable divide by 3
3b/3 = -5/3
3b divided by 3 is b, which is equal to -5 divided by 3; -5/3
b = -5/3 is your answer

Answer:
Solution given
let boys be x and girls be y.
now
according to the question;
x+y=575
and
y=x-54
substituting value of y in equation 1.
x+x-54=575
2x=575+54
x=629/2
x=314.5
