Question

x-y+3=0 ; 3x+y+1=0 linear equation ​

Answer 1

Step-by-step explanation:

☆Given☆

• X - Y = - 3
• 3X+ Y = - 1

☆To find ☆

• Value of X and Y

☆Solution☆

• X - Y = - 3 ---- (Equation 1)
• 3X + y = -1 ---- (Equation 2)

On adding both equation we get

⟹ 3X+X = -3-1

⟹ 4X = -4

$\sf \implies \: x = \bf\dfrac{4}{ - 4} \rightarrow - 1$

Putting X = - 1 in (equation 1)

⟹ -1 -y = -3

⟹ -1 +3 = Y

⟹ Y = 2

$\sf \bf{\huge \therefore} \: Value \: of \: X \: is \: -1 \: and \: value \: of \: Y \: is \: 2$
