5/10x = 2/10x + 15
5/10x - 2/10x = 15
3/10x = 15
x = 15 * 10/3
x = 150/3
x = 50
2/10(50) = 100/10 = 10 in. ....shortest piece
3/10(50) = 150/10 = 15 in .....middle piece
5/10(50) = 250/10 = 25 in .....longest piece

Answer:
Step-by-step explanation:o
x + y = 10........(1)
x - y = 14..........(2)
Adding (1) and (2)
2x = 24
x = 24/2
x = 12
And x + y = 10.......(1)
12 + y = 10
y = 10 - 12
y = -2
The number are 12 and -2
