Question

Fun Land theme park has a total of 140 males and females who are employed at the park. If the number of males is 20 more than twice the number of females, how many males are employed at the park?

Answer 1

m+f =140
m=20+ 2f

Solve for f in the first equation
f= 140 -m
Substitute in second equation
m=20 +2(140-m)
m=20 + 280 - 2m
3m = 300
m= 100
