Answer 1

ANSWER:

A = 7/2

B = 9/2

C = 19/2

D = 7/2

Answer 2

$\huge\sf\pink{Answer}$

☞ A = 3.5, B = 4.5, C = 9.5 & D = 3.5

━━━━━━━━━━━━━

$\huge\sf\blue{Given}$

✭ A + B = 8

✭ A + C = 13

✭ C - D = 6

✭ B + D = 8

━━━━━━━━━━━━━

$\huge\sf\gray{To \:Find}$

◈ The Value of A , B , C & D?

━━━━━━━━━━━━━

$\huge\sf\purple{Steps}$

So here with the given information,

≫ A + C = 13

≫ C = 13 - A$\;\;\;$ -eq(1)

So now of course we substitute the value of eq(1) in some other so now,

➝ C - D = 6

➝ 13 - A - D = 6

➝ - A - D = 6 - 13

➝ A + D = 7

Subtracting A + B = 8 from A + D = 7

➢ (A + B) - (A + D) = 8 - 7

➢ A + B - A - D = 1

➢ B - D = 1

And also we know that B + D = 8

So then the value of B = 4.5 & D = 3.5

➠ A + B = 8

➠ A = 8 - B

➠ A = 8 - 4.5

➠ A = 3.5

Similarly,

➳ C - D = 6

➳ C = 6 + D

➳ C = 6 + 3.5

➳ C = 9.5
