Question

2. यदि x + y +4x +4y+ 8 = 0 है तो (x+ Y)
बराबर होगा:​

Answer 1

$\huge{\underline{\tt Solution:-}}$

$\\ \tt{:}\dashrightarrow x+y+4x+4y+8=0$

• Combine like terms

$\\ \tt{:}\dashrightarrow x+4x+y+4y+8=0$

• Add accordingly

$\\ \tt{:}\dashrightarrow 5x+5y+8=0$

• Factor left side

$\\ \tt{:}\dashrightarrow 5(x+y)+8=0$

• Interchange sides

$\\ \tt{:}\dashrightarrow 5(x+y)=-8$

$\\ \tt{:}\dashrightarrow x+y=\dfrac{-8}{5}$

$\\ \tt{:}\dashrightarrow x+y=-1.6$

Answer 2

Answer:

x+y = -8/5

Step-by-step explanation:

given x+y+4x+4y+8= 0

5x+5y= -8

this implies 5(x+y) = -8

so x+y = -8/5
