Answer:
10 Females
23 Males
Step-by-step explanation:
First, lets write two equations based on the question:
M+F=33<em> - "a total of 33 students"</em>
M=F+13 <em>- "number of male is 13 more than the number of females"</em>
1) Now, lets substitute F+13 as M in our first equation: (M+F=33):
F+13+F=33
2) Combine alike terms:
2F+13=33
3) Subtract 13 from both sides:
2F=20
4) Divide both sides by 2:
F=10
5) Now we need to substitute 10 as the variable F in our second equation: (M=F+13):
M=10+13
6) Solve:
M=23
