McWhillion: dat foolish anti spam sha ..I cant see the solution clearly

Truck 1: N3500000, sells for N1000000 at 400050 km mileage
Truck 2: N5200000, sells for N1000000 at 544000 km mileage
Calculate the rate of depreciation of each vehicle:
Truck 1 => (3.5M -1M)/400050 = 6.249 N/km (approx)
Truck 1 => (5.2M -1M)/544000 = 7.721 N/km (approx)

At what mileage reading will the residual values of the two trucks be equal?
This is given in the question already .. 400050 and 544000 km??

At what mileage readings will both vehicles cost N500,000 each?
Truck 1: let that mileage be X => 3.5M - 6.249X = 0.5, solving for X=480,076 km
Truck 2: let that mileage be Y => 5.2M - 7.721X = 0.5, solving for Y=608,729 km

@McWhillion I think I solved the 1st problem, but NairaLand Antispam bot did not like my use of the Naira symbol and so my account got temporarily suspended
