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 = $2x + 3000$ $=2(38000) + 3000$ $=76000 + 3000 = 79000$
