Question 1016131: Using a system of 2 linear equations how do I solve this? Please help!!
An employment agency specializing in temporary construction help pays heavy equipment operators $140 per day and general laborers $90 per day. If thirty-five people were hired and the payroll was $3950, how many heavy equipment operators were employed? How many laborers?

Name the variables,
H-number of heavy equipment operators
L-number of laborers
Develop equations from the information,
Total number of workers:
1.H%2BL=35
Total payroll:
140H%2B90L=3950
2.14H%2B9L=395
Solve:
Multiply the first equation by 9 and subtract from the second.
14H%2B9L-9H-9L=395-9%2835%29
5H=80
H=16
Then from eq. 1,
16%2BL=35
L=19
