total acres = 79.
Number of Acres Tim gets = x
Acres of Tom = 2x - 20.
Acres of Tom + Acres of Tim = total acres
x + 2x - 20 = 79
3x = 99
x = 33
So Tim gets 33 acres.
Total Acres = Tim Acres + Tom Acres
79 = 33 + Tom Acres
Tom Acres = 79 - 33 = 46.
So Tom gets 46 acres.
PROOF ---
2(Tim Acres) - 20 = Tom Acres
2(33) - 20 = 46 acres.

2T-20=79
2T=79+20
T=99/2
T=49.5
Therefore we arrive at the conclusion based on the workout given above that Tom gets 49.5 Acres.

tom and tim = 79
tom = 2tim - 20
substitute first equation and solve -

(2tim-20) + tim = 79
