X=number of females
47-x=number of males
# of males is 2*(number of females)-7:
47-x= 2x-7
add x to both sides:
47=3x-7
add 7 to both sides:
54=3x
divide both sides by 3:
x= 18 females
47-18= 29 males
Answer:
33
Step-by-step explanation:
396/x - 10 = -22

396/x = -12
multiply both sides by x
396 = 12x
divide both sides by 12
33 = x
