Devante is 26 years younger than ariana. 2 years ago arianas age was 2 times devantes age. how old is devante now

A= d+26
a-2= 2(d-2)

Substitute for a
d+26-2= 2d-4

Combine like terms
d+24=2d-4

Subtract d from both sides
24=d-4

Add 4 to both sides
d=28

Final 28

Best answer that i found on yahoo ok   set :   x= length of 2nd piece in cm  x- 3= length of 1st piece in cm  x-4= length of 3rd piece in cm  then since you know they all came from the 20 cm ribbon you add them together and set them equal to 20x+ x-3 +x-4 = 20  3x - 7= 20  3x= 27  x= 9  the shortest piece is the third piece which is x- 4  x-4  9-4 = 5  the length of the smallest piece is 5 cm.  the other lengths are  9 cm  6 cm
