Question

A+B=420 B+C=380 C+D=340 D+E=330
THEN FIND A,B,C,D,E

Answer 1

some missing data

Step-by-step explanation:

A+B=420

B+C=380

C+D=340

D+E=330

There looks some missing data

as multiple solutions possible

For example

A = 220

A + B = 420

=> B = 200

B + C = 380

=> C = 180

C + D = 340

=> D = 160

D + E = 330

=> E = 170

A = 220  B  = 200  , C  = 180 , D = 160 ,  E  = 170

A + B + C + D + E = 930

Now Let say

A = 200

A + B = 420

=> B = 220

B + C = 380

=> C = 160

C + D = 340

=> D = 180

D + E = 330

=> E = 150

A = 200  B  = 220  , C  = 160 , D = 180 ,  E  = 150

A + B + C + D + E = 910

Now Let say

A = 210

A + B = 420

=> B = 210

B + C = 380

=> C = 170

C + D = 340

=> D = 170

D + E = 330

=> E = 160

A = 210  B  = 210  , C  = 170 , D = 170 ,  E  = 160

A + B + C + D + E = 920
