Answer
Telemarketers Jobs = 38000
File Clerk Jobs = 49000
Farmers/Ranchers Jobs = 79000
Work Step by Step
Let Telemarketers Jobs be $x$.
File Clerk Jobs $=x+11000$
Farmers/Ranchers Jobs = $2x + 3000$
Total decline of three jobs = $166000$
$x+x+11000+2x+3000 = 166000$
Group like terms.
$x+x+2x+3000 +11000= 166000$
$4x+14000= 166000$
Subtract both sides by $14000$
$4x+14000-14000= 166000-14000$
$4x= 152000$
Divide both sides by $4$
$x= 38000$
Telemarketers Jobs $(x)= 38000$
File Clerk Jobs $=x+11000$
$=38000+11000 = 49000$
Farmers/Ranchers Jobs = $2x + 3000$
$=2(38000) + 3000$
$=76000 + 3000 = 79000$
