Question

solve the following with the explanation aur direct answer ​

Answer 1

Answer:

a = 3.5

b = 4.5

c = 9.5

d = 3.5

Step-by-step explanation:

a + b = 8    ---- (1)

c - d = 6    --- (2)

a + c = 13 --- (3)

b + d = 8 --- (4)

a + b + c + d  = 13 + 8   ---- (3) + (4)

=> a + b + c + d = 21    

=> 8 + c + d = 21  ---- (1)

=> c + d = 13 ---- (5)

=> 2c = 13 + 6  --- (5) + (2)

=> c = 9.5

=> d = 13 - 9.5 = 3.5

=> a = 13 - 9.5 = 3.5

=> b = 8 -3.5 = 4.5
