Answer 2

☯ AnSwEr :

$\begin{lgathered}\boxed{a} + \boxed{b} = 14 \\ + \: \: \: \: \: \: \: + \\ \boxed{c} - \boxed{d} = 10 \\ | | \: \: \: \: \: \: \: \: \: \: | | \\ 15\: \: \: \: \: \: \: \: 16\end{lgathered}$

Now, we get

a + b = 14 ......(1)

a + c = 15 .......(2)

b + d = 16 ......(3)

c - d = 10.......(4)

↪From equation 1.

a = 14 - b

★ Put value of a in equation 2.

→ 14 - b + c = 15

→ -b + c = 15 - 14

→ -b + c = 1 .......(5).

$\rule{150}{2}$

↪From equation 3.

d = 16 - b

★ Put value of b in equation 4.

→ c - (16 - b) = 10

→ c - 16 + b = 10

→ c + b = 10 + 16

→ c + b = 26 .......(6)

$\rule{150}{2}$

↪From equation 5.

c = 1 + b

★ Put value of c in equation 6.

→ 1 + b + b = 26

→ 2b + 1 = 26

→ 2b = 26 - 1

→ 2b = 25

→ b = 25/2

→ b = 12.5

$\Large{\implies{\boxed{\boxed{\sf{b = 12.5}}}}}$

$\rule{200}{2}$

★ Put value of b in equation 1.

→ a + 12.5 = 14

→ a = 14 - 12.5

→ a = 1.5

$\Large{\implies{\boxed{\boxed{\sf{a = 1.5}}}}}$

$\rule{200}{2}$

★ Put value of a in equation 2.

→ 1.5 + c = 15

→ c = 15 - 1.5

→ c = 13.5

$\Large{\implies{\boxed{\boxed{\sf{c = 9.5}}}}}$

$\rule{200}{2}$

★ Put value of c in equation 4.

→ 13.5 - d = 10

→ -d = 10 - 13.5

→ -d = -3.5

→ d = 3.5

$\Large{\implies{\boxed{\boxed{\sf{d= 3.5}}}}}$

Now, we get

$\begin{lgathered}\boxed{1.5} + \boxed{12.5} = 14 \\ + \: \: \: \: \: \: \: \: \: \: \: + \\ \boxed{13.5} - \boxed{3.5} = 10 \\ | | \: \: \: \: \: \: \: \: \: \: \: \: \: \: | | \\ 15\: \: \: \: \: \: \: \: \: \: \: \: 16\end{lgathered}$
