Substitute the x-4 in to the second equation for the y:
2x+(x-4)=5
2x+x-4=5

Combine like terms and add the 4 to both sides
3x=9

Divide by 3:
x=3

Substitute the 3 in for x in either equation and solve for y:
y=3-4
y=-1

Answer:
x=3
y=-1

The 2 smallest lengths in a triangle have to add up to be greater that the longest side of the triangle. In this case, the longest side is 20. The 2 smallest sides are 5 and 10. 5+10=15, but 15<20. This is why these 3 lengths can’t create a triangle.
