Question

please solve this? ​

Answer 1

Answer :

E = 1/2

F = 7/2

A = 25 ×2

B = 5 × 2 /7

C = 4 ×2/7

D = 24 ×2

EXPLANATION

D = 24

E

=> D = 24 E ......1

=> C÷F = 4 => C = 4F ......2

=> put these values in last two equation

B-4F = F AND A - 24E = E

B = 5F AND A = 25E

=> replace value of A and B in first 2 equations and solve in terms of E and F get value of E and F

and sbstitute these to get value of A, B, C, D

25E +5F = 30 4F +24E = 26

5E + F = 6 2F + 12 E = 13 .....

10E +2F = 12 ......

WE GET

E = 1/2 and F = 7/2

buy getting these we can calculate others by putting these values in dark marked equation.
