Checking: 2x+x/2+(x/2-5)+4=3x-1Lengths: 2x, x/2, (x/2-5), 4
Did it wrongly, sry.....
Firstly, x is a natural number, rational number and is a integer. My x must be greater than 0 (No negative)
x can be 1-∞
Revised: x∈Z R N
The length of the 4 roads are: 1/2x, 1/2x, x, x-1....Check: 1/2x + 1/2x + x + (x-1) = 3x-1
Conditions: The lengths must be positive integers.
The length of the 4 roads are: x-10 km, x+4 km, x km, 5 kmCheck: (x-10) , (x+4) , x , 5 = 3x - 1
Conditions: x must be 10>
The lengths are: (x) km, (0.75x) km, (0.25x) km, (x-1) kmCheck: x + 0.75x + 0.25x + (x-1) = (3x-1) km
The conditions are: It cannot be 1 and belowCheck: (x-1) * If x is 1*(x-1) = 0 km * That is not possible for a road to be 0 km*Check: (x-1) * If x is 1.1*(x-1) = 0.1 km * That is possible for a road to be 0.1 km*
The possible lengths is (3x-1)/4 km for each of the road.
Check: (3x-1)/4 + (3x-1)/4 + (3x-1)/4 + (3x-1)/4 = (3x - 1) km
The possible lengths are 1 km, x+3 km,x+6 km, x-11 km. Check: (1+x+3+x+6+x-11) km = (3x-1) kmConditions: X cannot be 0, cannot be less than 11.

(3x-1)/4km * 4 = 3x-1km
x km +x km +x-10 km+9 kmCheck: x km +x km +x-10 km+9 km=(3x - 1) km.
The lengths are x km, x km x-10 km and 9km
My x is greater than 10.
(3x-1)/4km for each road. Since there are four roads, and each of the roads is (3x-1)/4, then the total of the four roads is obviously 3x-1km when you add them up together. Thank you you
The lengths of the roads are: 1 1/4 x km, x-1 km, 2/4 x km, 1/4 x km.Let's check with Chun Leong! 1 1/4 x + x-1 +2/4 x, 1/4 x km. YAY!
Ans : (3x-1)/4km.check:(3x-1)/4km+(3x-1)/4km+(3x-1)/4km+(3x-1)/4km=(3x-1)km
For (3x-1)/4, x must be 1 or larger.
The length of the 4 roads are: (2x-x)km,(3x-2x)km,(7x-6x)km,(7-7+1)kmCheck: (2x-x)km + (3x-2x) + (7x - 6x) + (7-7-1)= 3x - 1
x = >10
The possible lengths of the 4 roads are: 1/2x, 1/2x, x, x-1....Check: 1/2x + 1/2x + x + (x-1) = 3x-1
this is true if the variable is a positive integerXD
x km+ x km,+x-7 km,+6 km=3x-1
the possible lengths of the 4roads x,x,x+7,6
The length of the 4 roads are: (x-1) km, (0.8x) km, (0.2x) km, x kmCheck: (x-1) + (0.8x) + (0.2x) + x = 3x - 1
(4x - 3x +1 ) km + (7x - 6x -1) km+ (99 x -98x)km + -1kmCHECK:(4x - 3x +1 ) km + (7x - 6x -1) km+ (99 x -98x)km + -1km = 3x-1
Possible lengths of the 4 roads : 2 km, x-6 km, x+14 km, x-11kmCheck : (2+x-6+x+14+x-11)km = (3x-1)km
Try road 1 to be 0.5x, then road 2 as 1x-1 then road 3 as 1.25x and road 4 for 0.25xThese roads are of different lengths and they are measureable, they are not intergers but in decimal places. They all also add up to be 3x-1
my x is greater than 1
x km,x km,x-20km,19km This would only work if x is greater than 20km
The possible length of the four roads can be x km, x+15km, x-17km, 1 kmCheck: X km+x+15 km+x-17 km+1 km=3x -1x has to be greater than one for the lengths of the roads to be possible.
The possible length are: x km + (x-5)km + (x-2)km + 6kmCheck : x km + (x-5)km + (x-2)km + 6km= 3x-1
It will only work when x is greater than 5km
The possible lengths of the 4 roads are:x+2,x-2,x/2,x/2-1.Check:x+2+x-2+x/2+x/2-1=3x-1
